Q242509: InitiateSystemShutdown() Call May Not Shut Down the Computer

Article: Q242509
Product(s): Microsoft Windows NT
Version(s): winnt:4.0
Operating System(s): 
Keyword(s): kbWinNT400PreSP7Fix
Last Modified: 08-MAY-2002

-------------------------------------------------------------------------------
The information in this article applies to:

- Microsoft Windows NT Server version 4.0 
-------------------------------------------------------------------------------

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.
