SP4 and SP3 Terminal Server Bug Fix Here’s a Win2K Server Terminal Services bug that didn't get fixed in SP4 and thus can occur on both SP4 and SP3 systems. When a Terminal Services client logs on or off a client or console session, a server-based disk write-caching deadlock makes the server unresponsive for several seconds or longer, during which time the server can't process any other input. According to Microsoft, when the delay occurs, the client might show any of the following symptoms:
If you opt to install this fix, you can see the extensive list of modified files in the Microsoft article "Terminal Server and Connected Terminal Services Clients Pause When a Terminal Services Client Logs On or Logs Off" (http://support.microsoft.com/?kbid=324446). After you install the patch, you must also enable Power Protect on all hard disks on the Terminal Services system. You can query and change the Power Protect status of hard disks by using the dskcache.exe utility, which is available only from PSS. The Microsoft article "Obtain the Dskcache.exe Tool to Configure the 'Power Protected' Write Cache Option" (http://support.microsoft.com/?kbid=811392) describes how this utility works.
Win2K SP4 Citrix Logon Delay
Windows Explorer Bug Fix
• When a user is typing a document, characters don't appear on the screen until the server recovers from the deadlock.
• Keyboard input and mouse input are queued but not processed until the pause ends.
• Live Performance Monitor graphs have missing data points during the pause.
• All running programs appear to stop responding or hang during this pause.
• When Spooler is under a load from a large number of users, you'll see high CPU usage.
Have you noticed logon delays on Citrix clients after an SP4 upgrade? A printer redirection bug can cause delays of 5 to 30 minutes on systems running Terminal Services and either Citrix MetaFrame or Citrix 1.8. This problem occurs on systems on which you redirect a print queue to a local printer on the client system. If this description matches your configuration, you can call PSS and ask for the bug fix, which includes updated versions of 15 core OS files including msgina.dll, kernel32.dll, win32k.sys, and Winlogon. Most of the files in this patch have release dates of July 17, and you can get the update only from PSS. When you call, cite the Microsoft article "Very Long Logon Time When You Try to Connect to Citrix MetaFrame or Citrix 1.8" (http://support.microsoft.com/?kbid=824309) as a reference.
Every now and then, when you right-click a file to access the drop-down menu in either Windows XP or Win2K, Windows Explorer fails with the error message Windows Explorer has encountered a problem and needs to close. We are sorry for the inconvenience. Microsoft doesn't identify the bug that causes Windows Explorer to fail, but the company states that the problem occurs on XP SP1 and Win2K SP4 systems that run Windows Explorer 6.0.2800.1221. If this problem occurs frequently on your systems, you should see Dr. Watson messages about Windows Explorer in the System log. To correct the problem, call PSS and ask for the bug fix on either or both platforms; the fix updates three files: ole32.dll, rpcrt4.dll, and rpcss.dll. The updated files for XP have a file release date of July 22, and the Win2K versions have a file release date of July 21. You must reboot the system after you install the hotfix. For more information, read the Microsoft article "Windows Explorer Quits Unexpectedly or You Receive an Error Message When You Right-Click a File" (http://support.microsoft.com/?kbid=824136).
