Windows Update Service Uses All Resources

Anyone got any ideas on this?

Multiple servers, different OSes (2003, 2008R2). Different locations as well.

Some of our servers are getting stuck with the windows update service at 100%. Reboot or stop/start the service doesn't make any difference. As soon as the service starts, it goes to 100%. All our patches are manual. So it isn't the installation of a patch causing the problem. The network admins say they did a clean-up of the WSUS 3.0 server in the last few days, but that shouldn't affect our servers. Event viewer logs and windows update log look normal.

First part of the question: Any ideas of how to approach this?

Second part of the question: Somebody thinks there is a KB we should try and install manually. I downloaded it from MS, but in order to install it, Windows starts the update service, which of course spikes out the processor. Any way to install a patch without windows update turned on?

Edit: Ironically, I just found MS released a patch this month that talks about this type of problem, but installing it didn't help.

Have you looked in Event Viewer for info?  Any other error messages?

Run Process Explorer and see what else is running.

As I said, the event logs show nothing. When I stop the update service, the problem goes away.

Have you tried this MS Fixit?

Run SFC /SCANNOW from an admin Command Prompt.

If no help, you should consider a Repair Install

This should not affect your personal data or installed programs but a backup first is always a good idea.

The KB you suggested is for windows desktop, not server, but I'll review it and see if it is applicable.

As for the repair install, I can't see this being a solution since multiple servers have been affected.

Thanks.

Update: The steps from jcimarron didn't help. The issue has been escalated to Microsoft and they are examining the logs, so we'll see what happens.

Obviously it isn't something common since the MS WSUS team hasn't seen it. Meanwhile if anyone has any ideas, feel free to post.

Update: Microsoft really couldn't see any source of the problem either. Final solution was to create a new set of WSUS servers and change policy to use them.
