You may experience an abnormal shutdown, or "dirty shutdown," of your Microsoft Windows 2000 Server-based computer after the Windows logon screen saver starts. This abnormal shutdown may occurs if the following conditions are true:
You do not log on at the Windows logon screen after you start the computer.
You do not press a key or use the mouse.
You are running a program such as an uninterruptible power supply (UPS) support program that automatically calls the ExitWindowsEx function.
Additionally, after you restart the computer, you may receive the following event message in the system event log:
Event ID: 6008 Source: Event Log Description: The previous system shutdown at <time> on <date> was unexpected.
This problem occurs because the Windows Logon process (Winlogon.exe) does not ignore the Windows logon screen saver timeout. When the Windows logon screen saver timeout is not ignored, it causes an abnormal shutdown of your computer.
