SYMPTOMS

If two or more programs try to shut down or restart Windows, the computer that is running Microsoft Windows XP or Microsoft Windows 2000 may stop responding while it is shutting down. The desktop wallpaper may be visible and the mouse pointer may move, but the computer may not respond to keyboard input (including the CTRL+ALT+DELETE key combination). You might have to turn off the computer to continue. If Automatic Update is configured to install updates from Windows Update, from Microsoft Update, or from a Windows Server Update Service (WSUS) server, the Windows 2000 system may stop responding during shutdown or restart after you install updates.

CAUSE

If multiple programs call the ExitWindowsEx function to shut down or restart Windows at almost the same time, one of the shutdown messages may be discarded incorrectly. When this occurs, the shutdown process does not complete.
