Machine rebooting every night

Hi,

I have a users' machine that reboots every night. The event log shows that every night at 1145PM the machine attempts a reboot. The event log shows User32 as the source and 1074 as the event ID. The description of the event is listed below:

"The process winlogon.exe has initiated the restart of TVHOF24 for the following reason: No title for this reason could be found
 Minor Reason: 0xff
 Shutdown Type: reboot
 Comment: "


What could be causing this restart every night? The scheduled tasks folder is empty. The Anti Virus software is up to date.

thanks all,

What time everynight? same time? Are there any crash dumps?

Also, what is listed under this key in regedit?
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion\Winlogon\Notify
Darn, reread that and you had the time smack dab in front of my face....
Need to read slower...

I found a few links that reference winlogon.exe and reboots to virus/worm activity. (Sasser)
You stated that your anti-viurs is up to date. Have you performed a scan in Safe Mode?

I am curious why you suggested I check the registry for .....\Winlogon\notify?

What could winlogon have to do with the problem?


Thanks for the promptness!!

Just a quick search pulled that up, with some basic info...

And this is an article on the Shutdown Event Tracker

Oops, wrong thread, disregard the Shtdown event tracker link, doesnt apply to your problem....

Im on a roll, sheesh...

As for the Winlogon Key, I would be curious to see whats loaded by Winlogon each time it boots, to see if something is perhaps dormant...

How can I access that infomation? The registry I assume since it not in the event log.

John,

Thank you so much for your help. Unfortunately, I have yet to get access to the machine again.
I will write back with the registry info tomorrow.
