SYMPTOMS
The InitiateSystemShutdown function creates a shutdown message window that warns you to close all programs and log off. The message box has a timer that counts down to zero. If you do log off before the timer expires, the message window stays on the screen, usually behind the logon prompt. If you log on before the timer expires, the computer shuts down as expected. If you wait for the timer to expire before logging on, the window simply disappears and you can log on and continue with a normal session. This behavior is inconsistent with the documentation, which states that the computer will immediately shut down or reboot when you log off.



CAUSE
This behavior is caused by a problem in Winlogon.exe.
