1.0 INTRODUCTION

============================================================

This release of Microsoft Windows NT 4.0 Service Pack 5 (SP5) is easy to apply while Windows NT is running. SP5 updates all files that are older than those included in this Windows NT Service Pack. Service Pack releases are cumulative, containing all previous Service Pack fixes and any new fixes created after Service Pack 4. IMPORTANT: It's recommended that you stop running any critical services before you apply Windows NT 4.0 SP5. For more preinstallation recommendations, see Section 2.1, "Before You Install the Service Pack." IMPORTANT: SP5 contains only 40-bit encryption. This release isn't supported for installation on an existing North American 128-bit installation of Windows NT 4.0. If you install SP5 on a computer with 128-bit encryption, system services might fail to start. If you are on a North American computer, you may have 128-bit encryption installed. >>>To determine if 128-bit encryption is installed 1. Open My Computer, click View, and then click Options. 2. Click the View tab, select Show All Files, and click OK. 3. Click Start, point to Find, and then click Find Files or Folders. 4. Search for files named "Rsaenh.dll" on your local hard drives. 5. If the file exists in the System folder in your Windows NT folder, then you have 128-bit encryption support installed. If the file does not exist, you have 40-bit encryption. Installing the 40-bit version of SP5 on a previously existing 128-bit computer will not downgrade all of the encryption in the operating computer, so it will not necessarily change the exportability of the computer. ---------------------------- 1.1 What Is Service Pack 5? ---------------------------- SP5 is a collection of current updates and enhancements to Windows NT Server 4.0 and Windows NT Workstation 4.0 since their releases. SP5 is not a required upgrade. If you have deployed or are in the process of deploying a previous Service Pack, you probably need not change your plans. To accommodate customers in this situation, Microsoft provides software updates for critical issues to previous Service Packs. For example, you can continue to obtain Year 2000 (Y2K) software updates if you're using SP4. SP5 content is focused on: * Demonstrated customer impact SP5 rolls up many of the recent updates to Windows NT 4.0. In addition, SP5 has undergone extensive regression testing. The following is a list of the most frequently requested Windows NT 4.0 updates that are included in SP5: - DHCP Server of SP4 Ignores Reservations - SP4 forces cluster servers to be taken off and online - Windows NT 4.0 SP4 Does Not Update MTS Files - Duplicate SCSI Logical Unit (LUN) 0 When LargeLUNs Registry Key Enabled - Under stress, a computer running Windows NT Server or Workstation may display a STOP 0x0000001E error message on a blue screen. - Cannot configure ODBC logging when using Microsoft Data Access Components (MDAC) 2.0 SP1, SP4, and Proxy Server 2.0. - Secondary WINS query delayed by 1500ms even when primary WINS returns 'na - Using SP4, RCP "host:foo ." fails whereas RCP "host:foo foo" - SP4 systems access the hard disks every five minutes, which interferes with Power Management. * Y2K fixes SP5 provides the latest fixes to known Year 2000 issues in Windows NT 4.0. For more information on SP5 and Year 2000 issues, see Section 3.15, "Year 2000 Fixes." For the latest information on Year 2000 and Windows NT 4.0, see the Microsoft Year 2000 Readiness Disclosure & Resource Center Web site at http://www.microsoft.com/year2000/ or call 1-888-MSFT-Y2K. * Updates to SP4 issues, including: - Reduced heap fragmentation issues which would lead to memory problems. - Eliminated memory fragmentation problem with Critical Sections. - Eliminated a system hang that could occur on multiprocessor systems with multiple memory maps. - Resolved SP4 issues with Oracle Fail Safe software for Windows NT Clusters. - Eliminated hanging issues when SetSecurityInfo and SetNamedSecurityInfo calls were made during DLLInit time. - Enabled Desktop folders in Explorer windows to retain settings. - Eliminated issues where LPD would stop the printing of multiple copies. - Prevented DNS from converting host names to lowercase. - Prevented GetHostbyName from returning unbound IP RAS addresses. - Eliminated issues where Apple Macintosh Clients can't see Windows NT 4.0 Server after upgrading to SP4. - Eliminated issues where changing an SFM password allows Windows NT client computer to share access with null password. * Euro issues SP5 includes the existing updates for Windows NT 4.0 euro support. For the most recent information about Windows NT 4.0 and euro, see the Microsoft Euro Web site at http://www.microsoft.com/euro/. * Security updates SP5 contains current updates for known Windows NT 4.0 security issues. For the most recent information about Windows NT security, see the Microsoft Security Advisor Web site at http://www.microsoft.com/security/. ------------------------------------ 1.2 List of Fixes in Service Pack 5 ------------------------------------ To assist customers who are deciding whether to upgrade to SP5, Microsoft provides extensive documentation of the fixes and updates contained in SP5. This documentation gives customers the opportunity to analyze whether the SP5 contents justify the necessary test and deployment resources. This list of affected Service Pack files is available at http://support.microsoft.com/support/kb/articles/Q225/0/37.asp. ------------------------------------------------ 1.3 Downloading and Extracting the Service Pack ------------------------------------------------ If you have downloaded this Service Pack from an FTP site or a Web site, you should read the release notes completely before you extract and install the Service Pack. For this release, these self-extracting program files are also located at the root of the CD. They are SP5alpha.exe for Alpha processor type computers and SP5i386 for Intel- processor type computers. After downloading the Service Pack, you'll have a compressed program file on your hard drive. To extract this file and begin the installation process, for example, type SP5i386.exe at the command prompt, or double-click the file in Windows NT Explorer. You can also extract the file into the current folder without launching the installation program by using the command prompt switch /x. (For example, at the command prompt, type SP5i386 /x.)

============================================================

2.0 INSTALLATION INSTRUCTIONS FOR WINDOWS NT 4.0 SERVICE PACK 5

============================================================

Carefully read the installation instructions before you install Service Pack 5, since they may have changed from previous Service Packs. ---------------------------------------- 2.1 Before You Install the Service Pack ---------------------------------------- Close all active debugging sessions before installing this Service Pack, otherwise, the Update program is unable to replace system files that are in use. If a file is in use when you install SP5, a dialog box appears prompting you to cancel the installation or skip the file copy. It's recommended you cancel the installation and then uninstall SP5. To do this, run Spuninst.exe, or click Start, point to Settings, click Control Panel, double-click Add/Remove Programs, and then click Uninstall Service Pack 5. Close all active sessions on the computer, and then run Update.exe again to install the Service Pack. Also, to maximize recovery of the computer in the event of installation failure, it's recommended that you do the following before installing SP5: 1. Update the system Emergency Repair Disk by using the Rdisk.exe command with the /s switch. 2. Perform a full backup of the computer, including the registry files. 3. Disable any nonessential third-party drivers and services (that is, drivers and services that aren't required to boot the computer). 4. Contact the original equipment manufacturer (OEM) that provided the driver or service for the updated versions of the file(s). 2.1.1 NEC Versa 6050 or 6200 Series Notebook Computers ------------------------------------------------------ Users of NEC Versa 6050 or 6200 Series notebook computers, with Windows NT version 4.0 preinstalled, should select "Yes" when SP5 Update.exe prompts you to replace the Hal.dll file. 2.1.2 SystemSoft Card Wizard ---------------------------- If your computer contains SystemSoft Card Wizard version 2.x or earlier, you must obtain SystemSoft Card Wizard version 3.00.01 or greater before installing Windows NT 4.0 Service Pack 5. Otherwise, your operating system may no longer function. For further details, see the SystemSoft Web site at http://www.systemsoft.com/. 2.1.3 Advanced Power Management ------------------------------- Advanced Power Management isn't supported by Windows NT 4.0. As a result, it's recommended that you remove Advanced Power Management features before installing SP5. 2.1.4 Power Management Utilities -------------------------------- Power Management Utilities may not work on Windows NT 4.0 SP5. Contact the vendor of your Power Management Utilities for an updated version to work with Windows NT 4.0 SP5. -------------------------------------------- 2.2 Service Pack Install Order Documentation -------------------------------------------- IMPORTANT: If you are installing Service Packs for multiple Microsoft products, the order in which you install the Service Packs may have an effect on stability. You can view the documentation about the recommended installation order at http://www.microsoft.com/windows/servicepacks/. -------------------------------- 2.3 Installing the Service Pack -------------------------------- >>>To install the Service Pack from the CD 1. Insert the Service Pack CD into your CD-ROM drive. 2. If a Web page opens in your browser after you insert the CD, click Windows NT Service Pack, and then click Install Service Pack. 3. When you're prompted to open the file Spsetup.bat or save it to disk, click Open, and then follow the instructions that appear. Note: To use the uninstall feature of SP5, you must create an Uninstall folder during the initial installation. 4. If a Web page doesn't automatically open when you insert the CD, open the command prompt window, and change the folder to the drive letter associated with the CD-ROM drive. 5. Change the folder to \I386\Update or \Alpha\Update (depending upon whether you have an x86 or Alpha CPU), and type UPDATE. 6. Follow the instructions that appear. If SP5 doesn't install from the CD after you click Install Service Pack 5 or your browser doesn't automatically display installation instructions when you insert the CD into your CD-ROM drive, start the SP5 installation process manually from the CD. For more information, see "To Install the Service Pack from the CD" earlier in this section. >>>To install SP5 from a network drive 1. Run the command to connect to the network drive that has the SP5 files. 2. Change the drive letter to that of the network drive. 3. Change the folder to \I386\Update or \Alpha\Update (depending upon whether you have an x86 or Alpha CPU), and then type UPDATE. 4. Follow the instructions that appear. Note: It's recommended that you allow Setup to create an Uninstall folder the first time you install SP5. >>>To install SP5 from the Internet Use a Web browser (such as Internet Explorer 3.02 or later) to visit http://microsoft.com/windows/servicepacks/. Click the Install Service Pack 5 option to install SP5 on your computer. This Web page automatically detects which files need to be updated and then copies the appropriate files to a temporary folder on your computer. It then installs only those files that are needed to update your computer. Note: If you use Web browsers other than Internet Explorer 3.02 or later, you may be unable to install SP5 by using this update method. You can still install SP5 by downloading the entire Service Pack from the Internet onto your computer and running Update.exe locally. You can use installation switches with Update.exe. The following syntax help is available by typing update /?: UPDATE \[-u\] \[-f\] \[-n\] \[-o\] \[-z\] \[-q\] -u Unattended mode -f Force other programs to close at shutdown -n Do not back up files for uninstall -o Overwrite OEM files without prompting -z Do not reboot when installation is complete -q Quiet mode - no user interaction --------------------------- 2.4 Service Pack Uninstall --------------------------- This Service Pack contains an uninstall feature that you can use to restore your computer to its previous state. To enable the uninstall option, run Update.exe. A subfolder in your Windows NT folder named Uninstall is created. This requires at least 120 megabytes (MB) of free space on the drive on which Windows NT is installed, 60 MB for the uninstall folder, and 60 MB for the Service Pack-updated system files. To uninstall SP5, in Control Panel, double-click the Add/Remove Programs. Select Windows NT 4.0 Service Pack 5, and click Add/Remove. If this option isn't available, run Spuninst.exe from the \%systemroot%\$NtServicePackUninstall$\spuninst\ folder. Note: If you install any programs or services that require SP5 or have fixes contained in SP5, uninstalling SP5 could adversely affect those programs. To uninstall SP5, the drive letter for the boot drive must be the same one used when you installed SP5. If you change the drive letter for the boot drive, you can't uninstall SP5. To uninstall Service Pack 2 (SP2) and Service Pack 3 (SP3), you had to run Update.exe and then select "Uninstall a previously installed Service Pack." These commands returned your computer to its previous state. After your computer restarted, the Update.exe program replaced the files updated by the Service Pack with most of the files from the previous installation and returned most of your registry settings to what they were before that Service Pack was installed. Note: If you uninstall SP5 on a computer that previously had SP3 (without Internet Explorer 4.0) installed on it, cryptography won't work correctly after the uninstall completes. To work around this issue, reinstall SP3 after you have uninstalled SP5. Uninstalling SP5 won't uninstall new versions of CryptoAPI and SChannel. IMPORTANT: If you plan to install a previous Service Pack after uninstalling SP5, take note of the following important precaution. SP5 modifies the Security Account Manager (SAM) database and the Security database so that older versions of the Samsrv.dll, Samlib.dll, Lsasrv.dll, Services.exe, Msv1_0.dll, and Winlogon.exe files no longer recognize the database structure. Therefore, the uninstall process doesn't restore these files when uninstalling SP5. If you install a prior Service Pack (for example, SP3) after uninstalling SP5, click "No" on the "Confirm File Replace" dialog boxes that prompt you to overwrite Samsrv.dll and Winlogon.exe. If you overwrite the newer files with these older versions, you'll be unable to log on to the computer. Note: If you're reinstalling SP5 after installing new software or hardware, you must choose to create a new Uninstall folder. To retain your ability to return to a bootable configuration, copy the current Uninstall folder to a safe location before running the SP5 installation program.

3.0 USER NOTES

============================================================

This section covers information that is specific to Service Pack 5. -------------------------- 3.1 Emergency Repair Disk -------------------------- If you use the Windows NT Emergency Repair Disk to repair your Windows NT 4.0 computer, Windows NT requires you to supply the original Windows NT 4.0 media at some time after you install SP5. This means you'll need to reinstall SP5 after the repair is completed because the Emergency Repair Disk repairs your computer by restoring your original Windows NT 4.0 system files. After the repair is complete, follow the Installation Instructions (see Section 2.0) to reinstall SP5. For more information on using the Windows NT Emergency Repair Disk utility, go to the Microsoft Knowledge Base at http://support.microsoft.com/support/ and search for KB article Q146887. Note: To use the Emergency Repair Disk utility, you must have the updated version of Setupdd.sys which comes with SP5. To update your version of Setupdd.sys, copy Setupdd.sys from the Service Pack to your Windows NT 4.0 Setup Disk 2 from the original product media. This replaces the older version of Setupdd.sys with the updated version. For more information, go to the Knowledge Base at http://support.microsoft.com/support/ and search for KB article Q158423. -------------------------- 3.2 Adding New Components -------------------------- If you change or add new software or hardware components to your computer after you install SP5, you'll need to install SP5 again. This is because the files included on the original Windows NT 4.0 media may not be the same as the files on the Service Pack CD. You can't install new components, such as a new keyboard or printer driver, directly from the Service Pack media. You must install new components from the original product media and then reinstall the Service Pack. For example, if you install the Simple Network Management Protocol (SNMP) service after installing SP5, you'll need to reinstall the Service Pack. Otherwise, you'll receive the message "Entrypoint SnmpSvcGetEnterpriseOID could not be located in Snmpapi.dll." This informs you that some of the files in the SNMP service have been updated in SP5 and that you have a version mismatch. Reinstalling SP5 fixes the problem by copying the newer versions of the files onto your computer. Note: Simple Network Management Protocol (SNMP) security provides the ability to set a permission level on the SNMP agent computer. The permission level determines how the SNMP agent computer processes requests from an SNMP community. ---------------------------------------- 3.3 Installing Symbol Files from the CD ---------------------------------------- Each program file in Windows NT 4.0 has a corresponding symbol file that is helpful in diagnosing application and computer crashes. Symbol files are used in conjunction with a debugger and are not required proper operation of your computer. The symbols for SP5 files are compressed in self-extracting program files named Sp5symi.exe for Intel and Sp5syma.exe for Alpha0-based computers. To install the symbol files corresponding to the new binaries in SP5, run the executable file, and, when prompted, specify the path to the location of the previous version's symbols (for example, C:\Winnt\Symbols\). This command copies the SP5 .dbg files over the existing versions of these files. For more information about debugging in Windows NT, see Chapter 39, "Windows NT Debugger," in the Microsoft Windows NT 4.0 Workstation Resource Kit. ----------------------------------------------- 3.4 Hardware Compatibility with Windows NT 4.0 ----------------------------------------------- 3.4.1 Video Drivers ------------------- Due to incompatibilities between the ATIRage drivers and Service Pack setup, the files Ati.sys and Ati.dll are not included with SP5. Any ATI drivers currently installed on your computer still function normally. If you install SP5 over a previous Service Pack on a computer that has a Number Nine Visual Technologies Imagine 2 video card and drivers installed, you may experience some loss of functionality in the video driver, such as loss of any resolutions requiring 256 or more colors. If you uninstall SP5 and revert to SP3, the Imagine 2 card may be unable to display 256 colors or higher. There is no known resolution for either of these two issues because reinstalling the Imagine 2 video drivers doesn’t restore the lost functionality. Number Nine is aware of this issue and is working on a fix. 3.4.2 Dell Latitude Computers ----------------------------- If you're running Windows NT 4.0 on a Dell Latitude portable computer, your Dell-supplied Softex Advanced Power Management and PC Card Controller services (versions 2.0 and later) continue to function after you install SP5. Softex version 1.0 stops functioning after SP5 installation. To update your computer for SP5, install version 2.19 or later of the Softex utilities. Your computer becomes unusable if you reinstall any version of Softex prior to 2.19 after installing SP5.To download this utility, visit the Dell Web site at http://support.dell.com/filelib/. 3.4.3 Softex/Phoenix Utilities ------------------------------ If you're using any of the following Softex Incorporated or Phoenix Technologies utilities, you may encounter problems running SP5: * Softex PC Card Controller or Phoenix CardExecutive for Windows NT * Softex Power Management Controller or Phoenix APM for Windows NT * Softex Docking Controller or Phoenix NoteDock for Windows NT * Softex DeskPower Controller or Phoenix DeskAPM for Windows NT Follow these guidelines with Softex/Phoenix utilities: 1. Obtain the version number of the utilities you're using. 2. You must be running version 2.19 or later of the Softex or Phoenix utilities to avoid problems with SP5. Don’t install or reinstall any version of Softex or Phoenix utilities earlier than version 2.19 on your computer, or your computer might not start. For more information, see the Softex Incorporated Web site at http://www.softexinc.com/ or the Phoenix Technologies Web site at http://www.phoenix.com/. 3.4.4 Support for 255 SCSI Logical Unit --------------------------------------- Windows NT 4.0 detects only the first eight logical units on a SCSI device. To work around this limitation, install SP5 and add the following key in the registry: \HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services \\[Driver Service Key\]\Parameters\Device\[N\] LargeLuns: REG_DWORD: 0x1 where \[Driver Service Key\] is your SCSI driver name and \[N\] is the SCSI bus number. 3.4.5 SystemSoft Card Wizard ---------------------------- If your computer contains SystemSoft Card Wizard version 3.x and you have installed SP5, you may have lost socket services functionality. To work around this issue, reinstall SystemSoft Card Wizard version 3.x or higher after installing Service Pack 5. Or you can copy Pcmcia.sys from the Service Pack 5 Uninstall folder, $ntservicepacekuninstall$, to the \%systemroot%\System32\Drivers folder on your computer. Reboot the computer. ----------------------- 3.5 Compaq Alpha Notes ----------------------- 3.5.1 Using Remotely Possible 32 with Matrox Millennium Display Adapter --------------------------------------------------------------- If you use Remotely Possible 32 on an Alpha-based computer with a Matrox Millennium display adapter, don't use the Matrox drivers. Otherwise, your computer won't reboot properly. You must use VGA-compatible display adapter drivers to use Remotely Possible 32. 3.5.2 Lotus Notes 4.5 --------------------- If you want to use Lotus Notes and Internet Explorer 4.01 on an Alpha- based computer that runs Windows NT 4.0, you must follow this sequence when installing SP5: 1. If you have Internet Explorer 4.01 on your computer, uninstall it. 2. Install SP5. 3. Install (or reinstall) Lotus Notes. 4. Install Internet Explorer 4.01 SP2 from the SP5 CD. This problem will be fixed in a future release. 3.5.3 Alpha-based Fixes and Enhancements ---------------------------------------- The following sections describe fixes and enhancements to Alpha-based computers since Windows NT 4.0 SP3. Many of these fixes and enhancements are in the Hardware Abstraction Layer (HAL). SP5 ships with the latest version of HAL (revision E). This version is also available from Compaq as HAL V4.0 OEM revision E. IMPORTANT: If your computer has a Compaq KZPSA SCSI controller, revision E of HAL requires that you upgrade your DECKZPSX disk driver to V1.51 or later. Installing SP5 automatically installs the correct driver. 3.5.3.1 Computer Hangs on Alpha Systems with Only One Processor Physically Present The following Alpha-based computers with only one processor physically present no longer hang when booted: AlphaServer 4x00 AlphaServer 1200 AlphaStation 1200 Compaq Server 5000 Compaq Server 7000 3.5.3.2 Clock Interrupt Period Changed from 7.5 microseconds to 10 microseconds In Windows NT 4.0 SP5, the effective clock interrupt period on the following computers was changed from 7.5 microseconds to 10 microseconds: AlphaServer 4x00 AlphaServer 1200 AlphaStation 1200 Compaq Server 5000 Compaq Server 7000 This change provides parity with Intel-based computers and alleviates performance anomalies caused by assumptions of 10 microseconds for the resolution for timers (which are equal to the clock interrupt period). 3.5.3.3 Pyxis Error Registers HAL Revision D, which ships with Windows NT 4.0 SP5, supports updated Pyxis error registers, which provide more meaningful information during hardware crashes. 3.5.3.4 Peer-to-Peer DMA Transfers This Service Pack, together with the current AlphaBIOS firmware, now allows peer-to-peer DMA transfers. 3.5.3.5 PCI Devices with 256 MB of Memory or Greater The following Alpha platforms now support PCI devices with 256 MB of memory or greater for memory-mapped I/O: AlphaServer 1000 5/xxx AlphaServer 1000A 5/xxx AlphaServer 800 or Compaq Server 3000 AlphaStation 600 AlphaStation 500 Alpha XL 3xx 3.5.3.6 Alpha Computers That Used to Hang When Rebooting The following computers no longer hang during reboot: AlphaServer 4x00 AlphaServer 1200 AlphaStation 1200 Compaq Server 5000 Compaq Server 7000 3.5.3.7 I/O Performance Degradation or a Hung Computer Under Heavy I/O Loads On Alpha-based computers with heavy I/O loads, certain device drivers consumed too many DMA map registers. This sometimes caused poor I/O performance or a hung computer. SP5 allows a greater number of DMA map registers. 3.5.3.8 Crashes to Alpha-Based Computers with STOP Code 0x0A Minor "Correctable" Hardware errors no longer generate crashes with STOP code 0x0A on the following computers: AlphaServer 1000 5/xxx AlphaServer 1000A 5/xxx AlphaServer 800 or Compaq Server 3000 AlphaStation 600 AlphaStation 500 AlphaStation 600A Alpha XL 3xx 3.5.3.9 Improved Support for AlphaServer 4x00 and 1200 Computers HAL and system error-logging software allow these computers to store hardware fault data in the system event log for subsequent retrieval and analysis by service engineers or higher-level fault analysis software. 3.5.3.10 HAL Prevents Disk Corruption on AlphaServer 2100 5/xxx Computers I/O errors no longer cause disk corruption on these computers. 3.5.3.11 Crash Dumps can Complete without Hanging the Computer Parameter checking in IoFllushAdapterBuffer() allows for Diskdump.sys. This workaround allows crash dump operations to complete without hanging the computer. 3.5.3.12 HAL Traps VGA-mode Blue Screen Text HAL can trap VGA-mode blue screen text so that support engineers can get it from crash dump files by using kernel debuggers. 3.5.3.13 AlphaServer 1000A 5/xxx Computers Allow Disabled Warm Restarts To support Microsoft Cluster Server, you can disable warm restarts on these computers. In AlphaBIOS V5.68, you disable warm restarts in CMOS Setup, Advanced Settings. 3.5.3.14 Enhanced AlphaServer 2000, 2100, and 2100A Computers These computers avoid using bit 31 in DMA addresses and run when CPU slots are skipped. 3.5.3.15 Running UPDATE.EXE in Unattended Setup Mode (-u) To run UPDATE.EXE in unattended Setup mode by using the -u flag, you must also use the -o flag to ensure that OEM-supplied files are updated. If you don't use the -o flag, files such as HAL and disk miniport drivers are not updated. 3.5.4 Installation Fails on Alpha-Based Computers with Windows NT Option Pack 1.0 Installed ----------------------------------------------------------------- Security Configuration Manager (SCM) doesn't install on Alpha computers that have the Windows NT 4.0 Option Pack 1.0 for Alpha installed. This is because the Mfc42u.dll file installed by the Windows NT 4.0 Option Pack isn't compatible with SCM. To work around this issue, replace Mfc42u.dll installed by Windows NT Option Pack 1.0 for Alpha-based computers with Mfc42u.dll from the Windows NT 4.0 CD or from Visual C 6.0. This workaround may cause problems with the programs in the Windows NT 4.0 Option Pack 1.0 for Alpha-based computers. 3.5.5 Microsoft Transaction Server and Distributed Transaction Coordinator -------------------------------------------------------------- The file TestOracleXAConfig.exe isn't automatically installed on Alpha-based computers. If you are installing Windows NT 4.0 SP5 on an Alpha-based computer and are using Microsoft Transaction Server (MTS) or the Distributed Transaction Coordinator (DTC) with an Oracle or XA-compliant database, you must manually copy this file from the CD-ROM to the %sysroot%\system32 folder on your hard drive. The symbol %sysroot% represents the installation folder for Windows NT 4.0. For example, if your installation folder is C:\Winnt, you would copy it to C:\Winnt\System32. TestOracleXAConfig.exe is located in the \Alpha folder on the Windows NT 4.0 SP5 CD-ROM. If you are installing Windows NT 4.0 SP5 on an Intel-based computer, TestOracleXAConfig.exe is automatically installed during Setup. --------------------------------------------------------------------- 3.6 Running Windows NT 4.0 Administrative Tools from a Remote Server --------------------------------------------------------------------- To run administrative tools from a remote server, you must upgrade the remote server to SP5. If you try to run administrative tools from a remote computer that hasn't also been upgraded to SP5, they may fail to load or not function properly. ------------------------------- 3.7 CryptoAPI and Authenticode ------------------------------- The Authenticode environment won't be set up correctly for existing user accounts on upgrades from Windows NT 4.0 computers running Internet Explorer 3.02. This doesn't affect new user accounts created on the computer. Also, upgrades from Windows NT 4.0 computers with Internet Explorer 4.0 or later aren't affected. Users need to enter the following command line in a command prompt window before they use Authenticode: setreg 1 false 2 true 3 false 4 false 5 true 6 false 7 true 8 false 9 false 10 false Setreg.exe isn't part of SP5; you can download it as part of the CryptoAPI tools. You can install the latest CryptoAPI tools (Internet Explorer 4.0 or later) from the Platform SDK on MSDN. The CryptoAPI tools (also known as Authenticode Signing tools) that were released for Internet Explorer 3.02 are no longer supported. Tools released for Internet Explorer 4.0 continue to work with SP5. To ensure proper CryptoAPI functionality, it’s recommended that you install Internet Explorer 3.02 or later before you install SP5. The following is a list of known problems when Internet Explorer 3.02 or later is installed after SP5: * Certain CryptoAP2 networking functions depend on Wininet.dll and may fail if Wininet.dll isn't on the computer. To work around this, install Internet Explorer 3.02 or later before installing SP5. * Certain CryptoAPI-related file extensions (.cer, .crt, and .der) aren't registered correctly when Internet Explorer 4.0 is installed after SP5. To restore the file extension registration, run the following command line: Regsvr32.exe cryptext.dll This is fixed in Internet Explorer 5. ----------------------------------- 3.8 Uninstalling Internet Explorer ----------------------------------- On a computer that had Internet Explorer 4.0 or later installed and then had SP5 applied, uninstalling Internet Explorer partially removes newer CryptoAPI components. Reinstall SP5 after uninstalling Internet Explorer. This problem doesn't affect the computer if Internet Explorer was installed after SP5. ----------------------------- 3.9 Certificate Server Notes ----------------------------- 3.9.1 Known Problems and Limitations ------------------------------------ 1. Be sure to consult the release notes for the Certificate Server version 1.0 that were shipped with the Windows NT 4.0 Option Pack. For more information, go to the Knowledge Base at http://support.microsoft.com/support/ and search for KB article Q184695. 2. Do not perform an initial installation of Certificate Server on February 29th of a leap year. The validity period for the server is set incorrectly. To work around this, set the computer time to the previous day (February 28th), perform the installation, and then reset the computer time back to February 29th. There is no problem issuing certificates on February 29th once the Certificate Server is successfully installed (as noted above). 3. If you install Certificate Server over SP5, you may receive a "Some system services could not start" message upon startup. Click OK to continue, and check the Event Viewer log for the following errors. There are no workarounds. Event ID: 7000 Source: Service Control Manager Description: The Certificate Authority service failed to start due to the following error: "The service did not respond to the start or control request in a timely fashion." Event ID: 7009 Source: Service Control Manager Description: Timeout (120000 milliseconds), waiting for service to connect. 3.9.2 Virtual Directory Attributes for Certificate Server --------------------------------------------------------- IIS enforces the program attribute of virtual directories in such a way that the Certificate Server's administration Web pages fail. This failure appears in the form of database access errors that are identified by an E78 access failure code. You can't access the Certificate Server log and queue from the administration Web pages. To work around this problem, make sure that the program attribute for the Certificate Administration (CertAdm) folder is applied. >>>To apply the program attribute for CertAdm folder 1. Click Start, point to Programs, point to Windows NT 4.0 Option Pack, point to Microsoft Internet Information Server, and then click Internet Service Manager. 2. In MMC, expand the left pane entries until the Default Web Site is visible. 3. Double-click the Default Web Site. The right pane now contains the first level of virtual directories for the Web server. 4. Right-click the CertAdm virtual directory. 5. Click Properties. 6. On the Virtual Directory tab, in the Application Settings section, click Create. 7. Click Apply, and then click OK. 3.9.3 Invalid Hash Algorithm Accepted on Installation ----------------------------------------------------- During Certificate Server installation, don't select HMAC as the hash algorithm that the Certificate Server should use when it issues certificates. Although HMAC is among the selections on the optional Advanced Settings page, this isn't a valid use of this algorithm. If HMAC is selected, installation of the Certificate Server fails. For more information about Certificate Server, consult the Microsoft Knowledge Base. ------------------------------------------------------------------- 3.10 Internet Information Server 4.0, Secure Sockets Layer and Root Certifying Authority Certificates, and the IISCA.EXE Tool ------------------------------------------------------------------- If you use Internet Information Server 4.0 (IIS) with secure sockets layer (SSL) and you have installed a root certifying authority certificate (other than those issued by well-known third parties, such as Verisign, Thawte Consulting, or Microsoft), you may need to reinstall the affected root certifying authority certificates after you install SP5. You need to do this if you're using Microsoft Certificate Server 1.0, which shipped with the Windows NT 4.0 Option Pack. >>>To reinstall the root certifying authority certificate 1. Open Internet Explorer 4.0. 2. Browse to the root certifying authority certificate that you want to add. For example, for Microsoft Certificate Server, go to http://server/certsrv/CertEnroll/cacerts.htm, and click the root certifying authority certificate you want. 3. Select Open this file from its current location, and then click OK. 4. Click Install Certificate. 5. After the Certificate Manager Import wizard has started, click Next. 6. Select Place all certificates into the following store. 7. Click Browse, and then click Show physical stores. 8. Expand Trusted Root Certification Authorities, select Local Computer, and then click OK. 9. Click Next, and then click Finish. 10. Restart your Web server. Note: You no longer need to use the IISCA.exe tool. ------------------------- 3.11 Message Queue Notes ------------------------- A new MSMQ registry entry helps you configure the MSMQ Service to not try to contact the MQIS at startup (to avoid auto-dialing, for example). To activate that mode, under the "HKEY_LOCAL_MACHINE \Software\Microsoft\MSMQ\Parameters" registry key, add a value "DeferredInit", of type DWORD and with a value of 0x1. Add this only if the initial MQIS access causes unwanted dial-up because this setting can delay programs calling MQOpenQueue in offline situations. --------------------------- 3.12 COM Internet Services --------------------------- 3.12.1 Installing COM Internet Services --------------------------------------- COM Internet Services (CIS) provides facilities for making DCOM calls over the Internet when other transports can't be used due to a firewall on the server side or a proxy server on the client's network. There are three configuration options for CIS: * Windows 95 or Windows 98 CIS Client Support * Windows NT 4.0 SP5 and Windows 2000 CIS Client Support * Windows NT 4.0 SP5 and Windows 2000 CIS Server Support This section explains how to install CIS on computers running Windows NT 4.0 SP5. If possible, you should start with client and server computers that aren't separated by either proxy servers or firewalls. Once you have verified that this configuration works correctly, you can add proxy servers or firewalls to the configuration. 3.12.2 Windows NT 4.0 SP5 CIS Client Support -------------------------------------------- For Windows NT 4.0, CIS requires that SP5 be installed on your Windows NT Workstation 4.0 or Windows NT Server 4.0 computer. To enable CIS, you need to add the Tunneling TCP protocol to the DCOM protocol list. You can modify the protocol list by running DCOMCNFG: 1. Select the Default Protocols tab. 2. Use the Add button to add Tunneling TCP/IP. 3. Restart the computer for this change to take effect. If multiple protocols are configured, DCOM tries to use them in the order in which they appear in the DCOM protocol list. CIS also requires that Internet Information Server 4.0 (including the Internet Service Manager) be running. IIS 4.0 is part of the Windows NT 4.0 Option Pack. >>>To add the Tunneling TCP protocol to the DCOM protocol list 1. Create an RPC subfolder under your Inetpub folder. For example, at the command prompt, type md c:\inetpub\rpc This folder is referred to as %inetpub%\rpc in the following steps. 2. Copy Rpcproxy.dll from the Windows system folder to %inetpub%\rpc. For example, at the command prompt, type copy %windir%\system32\rpcproxy.dll c:\inetpub\rpc 3. Create a virtual root for the folder you created. To do this: * Click Start, point to Programs, point to Windows NT 4.0 Option Pack, point to Microsoft Internet Information Server, and then click Internet Server Manager. * In the left pane of the MMC window, select Console Root/IIS/ /Default Web Site. * Right-click Default Web Site, click Create New, and then click Virtual Directory. * In the New Virtual Directory wizard, enter the following: alias to be used to gain access to virtual directory = rpc physical path = %inetpub%\rpc permissions = Execute Access 4. Don't close Internet Service Manager. Change the connection timeout for the Default Web Site to 5 minutes. To do this: * In the left pane of the MMC window, select Console Root/IIS/ /Default Web Site. * Right-click Default Web Site, and then click Properties. * In the Default Web Site Properties dialog box, select the Web Site tab. * Change the Connection Timeout to 300. * Click OK. Do not close Internet Service Manager. * Install the RPC Proxy ISAPI Filter. To do this, run the IIS 4.0 Internet Service Manager, select Console Root/IIS/ in MMC, right-click the computer name, click Properties, select Edit for the Master WWW Service Properties, select the ISAPI Filters tab, select Add, and then type: filter name = Rpcproxy executable = %inetpub%\rpc\rpcproxy.dll 5. Close Internet Service Manager now. 6. Enable CIS on the server. You do this by running DCOMCNFG. To do this: * Click Start, and then click Run. * In the Run dialog box, type dcomcnfg, and then click OK. * In the left pane of the MMC window, select the Default Properties tab. * Make sure the check box labeled Enable COM Internet Services on this computer is checked. Don't close DCOMCNFG. 7. Add the Tunneling TCP protocol to the protocol list. You can modify the protocol list by running DCOMCNFG. To do this: * Click Start, and then click Run. * In the Run dialog box, type dcomcnfg, and then click OK. * In the left pane of the MMC window, select the Default Protocols tab. * Use the Add button to add Tunneling TCP/IP. * Close DCOMCNFG. 8. Restart your computer for these changes to take effect. 3.12.3 Notes on Proxy Servers ----------------------------- If your client is located behind a proxy server, you need to ensure that: * The proxy server is configured to enable the HTTP CONNECT verb for port 80. * Your client computer is correctly configured to use the proxy server to gain access to the World Wide Web. To configure your client to use the proxy server, use the Internet control panel. 3.12.4 Notes on Firewalls ------------------------- CIS requires that the firewall let TCP/IP traffic through on port 80. ----------------------- 3.13 Event Log Service ----------------------- SP4 introduced new features in the Event Log Service to assist administrators in measuring the reliability and availability of Windows NT 4.0. When running SP4 or later, the SP5 Event Log Service records the following three new events in the system event log that are useful in measuring operating system availability: 3.13.1 Clean Shutdown Event (Event ID: 6006) -------------------------------------------- The Event Log Service records a clean shutdown event whenever an operating system shutdown is initiated. Several mechanisms can initiate a clean shutdown: * Direct user interaction using the Shut Down screen * Shutdown/Restart using CTRL+ALT+DELETE * Shutdown/Restart using the Start Menu * Shutdown/Restart using the Logon screen Clean shutdowns are also recorded if one of the following shutdown events happens programmatically: * InitiateSystemShutdown WIN32 API (local) or * InitiateSystemShutdown WIN32 API (remote). 3.13.2 Dirty Shutdown Event (Event ID: 6008) -------------------------------------------- The Event Log Service records a dirty shutdown event whenever the operating system is shut down by a mechanism other than a clean shutdown. This most commonly occurs when the computer is power-cycled; that is, you stop Windows NT 4.0 by powering off the computer. The event is recorded upon the subsequent reboot. While Windows NT 4.0 Server is running, the computer periodically writes a time stamp to the registry. This time stamp always overwrites the "last alive" time stamp from the previous interval. When the "last alive" time stamp is written, it's also flushed to disk. A normal, clean shutdown is also flagged in the registry. If the clean shutdown flag isn't found on disk when an SP5 computer reboots, a dirty shutdown event is recorded. The description part of the event contains the "last alive" time stamp. The "last alive" time stamp is written to the registry at a default interval of five minutes to HKLM\Software\Microsoft\Windows \CurrentVersion\Reliability\LastAliveStamp. Adding the registry DWORD value TimeStampInterval can change the interval. This value is in units of minutes. Setting it to zero prevents any "last alive" time stamp logging. Only the boot and normal shutdown stamps are written in that case. 3.13.3 System Version Event (Event ID: 6009) -------------------------------------------- The Event Log Service records a system version event containing the operating system version information whenever the computer is booted. This record makes it easier to post-process Windows NT system event logs by operating system version. Note: Prior to SP5, the recording of operating system crashes in the event log (Save Dump events) was optional. By default, crash events were recorded, but a system administrator could disable this behavior in the System control panel by clearing "Write an event to the system log when a STOP error occurs" on the Startup/Shutdown tab. In SP5, the recording of crashes in the event log is mandatory for Windows NT Server and can't be disabled by an administrator. However, there is no change for Windows NT Workstation; an administrator can still choose either setting. ------------------------------------------- 3.14 Upgrading a Cluster to Service Pack 5 ------------------------------------------- 3.14.1 Rolling Upgrade ---------------------- You can eliminate the downtime of your cluster services and minimize administrative complexity by performing a rolling upgrade of the operating system. In a rolling upgrade, you sequentially upgrade the operating system on each node, making sure that one node is always available to handle client requests. A rolling upgrade consists of four phases: * Phase 1: Preliminary Each node runs Windows NT 4.0 SP3. * Phase 2: Upgrade Node 1 Node 1 is paused, and Node 2 handles all cluster resource groups while you upgrade the operating system of Node 1 to Windows NT 4.0 SP5. * Phase 3: Upgrade Node 2 Node 1 rejoins the cluster. Node 2 is paused, and Node 1 handles all cluster resource groups while you upgrade the operating system on Node 2 to SP5. * Phase 4: Final Node 2 rejoins the cluster. The operation of Phase 3, when the two cluster nodes run different Service Packs, is called a "mixed-version cluster." It's recommended that you ensure that every resource on your cluster can operate in a mixed-version environment. If version incompatibilities prevent a cluster resource from operating in a mixed-version cluster, you won't be able to successfully complete your rolling upgrade. Note: You can't create new groups, resources, or resource types in a mixed-version cluster. >>>To perform a rolling upgrade 1. Pause the cluster service on Node 1, and move its resource groups to Node 2. 2. Upgrade Node 1 from SP3 to SP5. 3. Perform validation tests on Node 1 to certify that the node is fully functional. 4. In Cluster Administrator, click Resume Node. 5. Repeat steps 1 through 4 for Node 2 instead of Node 1. 3.14.2 Alternatives to a Rolling Upgrade ---------------------------------------- There are two alternatives to a rolling upgrade for upgrading Windows NT 4.0 on a cluster. If you can't perform a rolling upgrade because your cluster manages a resource that is incompatible with rolling upgrades, consider taking the incompatible resource offline, performing a rolling upgrade, and then installing the new version of the resource. If most of your cluster resources are incompatible with a rolling upgrade, you should consider a clean install of Microsoft Cluster Server. If you do this, you must reconfigure your cluster after the installation. >>>To perform a clean install of Microsoft Cluster Server 1. Following the procedure described in Cluster Administrator Help, stop the cluster service on Node 1. On Node 1, uninstall Microsoft Cluster Server. 2. Stop the Cluster Service on Node 2. On Node 2, uninstall Cluster Server. At this point, the cluster that was running on Node 1 and Node 2 no longer exists. 3. Reinstall Cluster Server on Node 1 using the Windows NT 4.0 Enterprise Edition Components CD, and then form a new cluster using the name of the original cluster. 4. Reinstall SP5 and perform validation tests on Node 1. SP5 upgrades the original SP3 clustering product to SP5. 5. Reinstall the Cluster Server on Node 2 using the Windows NT 4.0 Enterprise Edition Components CD and then join the newly formed cluster. 6. Reinstall Cluster Server and then perform validation tests on Node 2. 7. Using Cluster Administrator, add cluster resources to your new cluster. 3.14.3 Known Clustering Issues ------------------------------ You won't be able to select or clear the Use network name for the computer name check box on the Generic Service Parameters tab if you change the value for the resource from its original setting. The service uses the network name for the computer name, regardless of the check box value. To fix the problem, open Regedt32, and edit the following key on all the cluster nodes: HKLM\SYSTEM\CurrentControlSet\Services\\Environment This is a multiline string. Remove the line containing _CLUSTER_NETWORK_NAME_. ---------------------- 3.15 Year 2000 Updates ---------------------- SP4 and SP5 contain updates for known Year 2000 issues for Windows NT 4.0: * The User Manager and User Manager for Domains recognize the year 2000 as a leap year. * The Date/Time Control Panel applet can update the system clock. * Find Files supports only numeric character recognition in the decades field. * Word document properties recognize both 1900 and 2000 as valid centuries and support four-digit years. * The Dynamic Host Configuration Protocol (DHCP) administrators’ program supports displaying the years 2000 through 2009 with a minimum of two digits. SP5 is not required for Year 2000 Compliance. Microsoft is committed to maintaining SP4, SP5, and future Service Packs as Year 2000 compliant. Note: In order to simplify the upgrade process, the SP4 Y2ksetup.exe composite patch is no longer included in the recommended upgrade path. Y2ksetup.exe was used to update the following Windows NT 4.0 components: * Internet Explorer * Microsoft Data Access Components (MDAC) * Site Server Express With SP5, it's recommended that you install any needed updates these components individually. To determine which updates, if any, that you need, see the Year 2000 Readiness Disclosure & Resource Center Web site at http://www.microsoft.com/year2000/ or call 1-888-MSFT-Y2K. Do not install Y2ksetup.exe after you install SP5. The Microsoft Year 2000 Product Analyzer scans a hard or network drive to report the Year 2000 compliance levels of Microsoft products and if updates are required, the report provides links to product-specific update information. You can download the Microsoft Year 2000 Product Analyzer at the Microsoft Year 2000 Readiness Disclosure & Resource Center Web site at http://www.microsoft.com/year2000/. For the latest Year 2000 information regarding Microsoft products, visit the Microsoft Year 2000 Readiness Disclosure & Resource Center Web site at http://microsoft.com/year2000/. You can also call toll-free 1-888-MSFT-Y2K within the United States or contact your local Microsoft subsidiary. -------------------------------------------- 3.16 Uninstalling IE 4.01 SP2 if using MSSCE -------------------------------------------- If you install Internet Explorer 4.01 SP2 and the Microsoft Security Manager (also known as the Microsoft Security Editor, or MSSCE), you may not be able to uninstall Internet Explorer. Instead, you receive the following message: "OLEMainThreadWndNmame: SETUP.EXE -Entry Point Not Found The procedure point GetVersionFromFileEx could not be located in the dynamic link library ADVPACK.dll." This is because the install programs for Internet Explorer and MSSCE require different versions of the file Advpack.dll. Complete the following procedure to use the version of Advpack.dll that allows you to uninstall Internet Explorer: 1. Open a command prompt window. 2. Create a folder by typing "md c:\temporary" (without the quotes) and pressing Enter. 3. Change to the temporary folder by typing "cd \temporary" and pressing Enter. 4. Type "copy c:\Internet Explorer 4.01 Sp2 Setup\setupnt.cab" to create a copy of the file containing Advpack.dll. 5. Type "extract setupnt.cab advpack.dll" to create a copy of Internet Explorer's Advpack.dll file. 6. Copy this Advpack.dll to the \%systemroot%\System folder inside your Windows NT folder. On most computers, you can type "copy advpack.dll c:\winnt\system". ------------------------------------------------------------- 3.17 Find Files or Folders by Date using Dates Prior to 1980 ------------------------------------------------------------- Find Files or Folders by Date does not properly search for files dated prior to 1980. The Find Files or Folders utility is accessible from the Start menu. If finding files by date using a date range prior to 1980, no files will be listed. If searching for files within a date range that spans 1980, all files are listed. Searching on files dated 1980 through 2035 works correctly. You will not encounter this problem if using the Internet Explorer 4.0 Desktop Update. For more information, go to the Knowledge Base at http://support.microsoft.com/support/ and search for KB article Q229313.
