This week, I describe the Mozilla Web browser, explain which keyboard shortcuts you can use with Microsoft Internet Explorer (IE) and Mozilla Firebird, and tell you why you might receive an error on start-up that says the system can't find system32.exe in the system32 folder. I also explain why you might receive a warning in the event log that a provider has registered in the Windows Management Instrumentation (WMI) namespace, how to retrieve core Windows files that you've deleted, and how to quickly determine whether a domain controller (DC) is available for a specific domain.

Q. What's Mozilla?
A. Mozilla is an alternative to Microsoft Internet Explorer (IE) that's recently undergone some big enhancements. You can download the latest version (Mozilla 1.4) or get the lean version (Mozilla Firebird 0.6) at http://www.mozilla.org. Mozilla Firebird doesn't require installation--you just unzip the downloaded package to a folder and run the software from there.
Some of Mozilla's features include
- tabs to load multiple Web sites instead of opening separate instances of the application for each Web site
- a built-in pop-up ad blocker
- tools to better control information that the browser receives, such as a tool that prevents Web sites from modifying the Web browser status bar, which typically displays the Web site address
- a search box for searching public search engines, such as Google
- automatic import of IE bookmarks
- support for all leading standards (e.g., HTML) and plugins
After using Mozilla for a day, I was impressed by its clean interface, speed, and flexibility. I particularly liked the tabbed browsing feature. Give it a look.
Q. What keyboard shortcuts can I use with Microsoft Internet Explorer (IE)6 and Mozilla Firebird 0.6?
A. The following table lists the most popular keyboard shortcuts:
|Action||Internet Explorer||Mozilla Firebird|
|Go to www.
|Go to www.
|Go to www.
|Find on page||Ctrl+F||Ctrl+F|
|Full screen (toogle)||F11||F11|
|Move to next tab||Ctrl+Tab|
|Move to previous tab||Ctrl+Shift+Tab|
|Reload (don't use cache)||Ctrl+F5||Ctrl+Shift+R/Ctrl+F5|
|Select location bar||Alt+D/F4/F6/Ctrl+Tab||Alt+D/F6/Ctrl+L|
|Select search bar||Ctrl+K|
|Select tab||Ctrl+\[1 to 9\]|
Q. Why do I receive an error on start-up that says the system can't find system32.exe in my system32 folder?
A. More than likely, your machine was infected by the system32.exe virus, which your antivirus software removed without removing the startup entry in the registry. To resolve this error, perform the following steps:
- Start a registry editor (e.g., regedit.exe).
- Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run registry subkey.
- Select the "Explorer.exe C:\Windows\system32\system32.exe" entry, then click Delete (the path for this registry entry might be slightly different on your machine, depending on the folder in which you installed Windows).
- If you see a registry entry for cmd32.exe, remove it as well.
- Click Yes in the confirmation dialog box.
If you can't find the registry entry I describe in Step 2, review this FAQ for a list of other registry locations you can search.
Q. Why do I receive a warning in the event log that a provider has registered in the Windows Management Instrumentation (WMI) namespace?
A. The message you describe reads
, has been registered in the WMI namespace, , to use the LocalSystem account. This account is privileged and the provider may cause a security violation if it does not correctly impersonate user requests.
Q. How can I retrieve core Windows files that I've deleted?
A. Although you can manually copy the files from the Windows installation media, you're probably better off using the System File Checker utility that ships with Windows 2000 and later. If you've changed your configuration since you installed Windows and your installation media is now available at another location, you'll need to perform the following steps before you run System File Checker:
- Start a registry editor (e.g., regedit.exe).
- Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion registry subkey.
- Change the Sourcepath value to point to the installation media's new location (e.g., D:\i386).
- Navigate to the HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Setup registry subkey.
- If the Sourcepath value is listed, change the value here also to point to the installation media's new location.
To use System File Checker, perform the following steps:
- Insert the Windows CD-ROM installation media.
- From the Start menu, select Run.
to start the System File Checker process and check all core files. The utility will replace any missing core files and make sure all the files are up-to-date.
Q. How can I quickly determine whether a domain controller (DC) is available for a specific domain?
A. To quickly check for a DC in a specific domain, go to the command prompt and type
If your search is successful, the system will display information about that DC. For example,
C:\>nltest /dsgetdc:savilltech DC: \\TITANIC Address: \\22.214.171.124 Dom Guid: 9819e7e4-7beb-41d9-9923-dac38b1d342a Dom Name: SAVILLTECH Forest Name: ADS.SAVILLTECH Dc Site Name: UK Our Site Name: UK Flags: DS LDAP KDC TIMESERV WRITABLE DNS_FOREST CLOSE_SITE The command completed successfully
If your search fails, you'll receive a failure notice, such as
C:\>nltest /dsgetdc:test1 DsGetDcName failed: Status = 1355 0x54b ERROR_NO_SUCH_DOMAIN
