My thanks to all who have replied. I will try the hotfix referenced in Willian Balluff's message on a few remaining machines having the problem today, and see if it truely resolves the issue. Barring that I will disable MSOffice updates and stick to just the critical OS patches. Thanks again to everyone for all your help and suggestions. /John Resotko, MSU College of Law >>> "Balluff, William" <[log in to unmask]> 5/9/2007 12:24 PM >>> John, We started seeing this last fall. This is the fix I posted on msunag in Feb.

The problem is related to Microsoft updates. Before the update, we had to disable Microsoft update and enable Windows update and that fixed the problem. If the hotfix does not fix the problem, disable Microsoft updates by bringing up Microsoft updates, Change settings, scroll to the bottom and check disable Microsoft Update software and let me use Windows Update only. Sometimes you get the problems Peter explained, other times you get Svchost.exe error. -----Original Message----- From: [log in to unmask] [mailto:[log in to unmask]] On Behalf Of Peter J Murray Sent: Friday, February 23, 2007 4:08 PM To: [log in to unmask] Subject: speaking of Vista...XP problem While I don't think Vista is the devil (it's actually pretty nice), I am having a vexing XP problem on a couple of workstations. On two of our workstations (both freshly reformatted about two months ago) with XP SP2, I'm having a weird problem where a bunch of services (workstation, windows audio, ICS firewall) will shutdown after about 5 minutes after boot. I can tell this is happening because the themes service will shutdown and restart and then the computer starts acting all weird (so you get a few moments of 'old windows' until themes comes backup). Network activity gets all screwed up and network drives are dismounted after this incident, sound won't work, but most of the services can be restarted with the exception of ICS. No spyware or viruses are on these machines. Any ideas?
