No Desktop or Blank Desktop After Logging On to Windows 2000

The information in this article applies to:

Microsoft Windows 2000 Professional

SYMPTOMS
When you log on to Windows 2000, you may see a blank desktop or no desktop. When this occurs, you can press CTRL+ALT+DELETE to start Task Manager, but Explorer.exe is not listed in the list of running tasks or processes. Starting a new instance of Explorer.exe does not resolve the issue.

CAUSE
This behavior can occur if there is an older version of the Shdocvw.dll file in the %SystemRoot% folder. Because Explorer.exe is located in the %SystemRoot% folder, the search path for any called files starts in the %SystemRoot% folder before the path is searched. The default search order always looks for a called file in the folder containing the program file before searching the path to locate the file.
RESOLUTION
To resolve this issue: Press CTRL+ALT+DELETE, and then click Task Manager.
On the File menu, click New Task (Run).
Type cmd.exe, and then press ENTER.
If necessary, change to the %SystemRoot% folder. This is typically the Winnt or Windows folder.
Rename the Shdocvw.dll file by typing ren shdocvw.dll shdocvw.old.
Restart the computer.


MORE INFORMATION
Other older files that may cause problems with Explorer.exe or the shell if they are located in %SystemRoot% folder: Browseui.dll
Comctl32.dll
Comdlg32.dll
Mlang.dll
Ole32.dll
Oleaut32.dll
Shdocvw.dll
Shell32.dll
Shlwapi.dll
Urlmon.dll
Wininet.dll
Setupapi.dll

The desktop may also be blank if your computer is configured for multiple monitors and the icons are on a portion of the desktop that is outside the viewable range. Check the properties for the video adapter, and then click Settings. If two monitors are displayed, but only one is in use, click the first monitor, and then check the settings. If the Extend my Windows desktop onto this monitor check box is selected, click to clear the check box, and then click Apply. The icons should then reappear.
