256986 Description of the Microsoft Windows Registry
SYMPTOMS
When you attempt to log off or shut down a server while a command prompt session is still open, the computer may appear to stop responding (hang). When this occurs, you receive the following error message:
If you click End Task, the computer pauses for 10 minutes before closing the command window, but does not log you off or shut down. If you click Wait, the command window does not close. If you click Cancel, the command window closes and you are returned to the desktop.
CAUSE
This behavior can occur if the server is deadlocked because of an inappropriate number of CSRSS threads available. This can be caused by a invalid registry entry that is created when you install Seagate Backup Exec version 7.0 build 719.
RESOLUTION
WARNING: If you use Registry Editor incorrectly, you may cause serious problems that may require you to reinstall your operating system. Microsoft cannot guarantee that you can solve problems that result from using Registry Editor incorrectly. Use Registry Editor at your own risk.
To resolve this issue:
- Start Registry Editor (Regedt32.exe).
- Locate the following key:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Session Manager\SubSystems\Windows
The data for this value looks something like the following sample data:
%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,3072 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads
- Add =16 after "MaxRequestThreads" so that the data looks similar to:
%SystemRoot%\system32\csrss.exe ObjectDirectory=\Windows SharedSection=1024,3072 Windows=On SubSystemType=Windows ServerDll=basesrv,1 ServerDll=winsrv:UserServerDllInitialization,3 ServerDll=winsrv:ConServerDllInitialization,2 ProfileControl=Off MaxRequestThreads=16
- Quit Registry Editor.
- Reboot the computer.
