Lsass.exe at constant 99% CPU ultilization

[Daveyd123]

I have a member server running 2003 SP2. It also has SQL 2000 installed on it as well as Document Imaging application that uses SQL.

I am not sure what happened but all of a sudden users are complaing that accessing the document imaging application from their workstations was extrelemy slow. Looking at Task Manager, the lsass.exe process is pegged at 99%.

Trying to do some research on it, most articles refer to the issue being on a DC. Well, this is not a DC and I'm still having issues.

I've run Process Monitor and Process Explorer trying to extract more info. Any ideas how to track down why the process is pegged at 100%?

Start with checking the event log. I have seen this happen with a lot of different types of apps (and viruses/worms).

Event log shows no problems. No viruses. Removed Mcafee via ePO.
