Yes, unfortunately, it's caused by Sasser or one of it's variants. I've worked on 3 Sasser victims in the past two weeks.
The LSASS service (process) in the operating system is being hit.
Go to symantec.com for removal instructions. Run the FxSasser & also check for the other symptoms discussed. Also you will have to upload the Windows Critical Updates from Microsoft for the OS to stop it from reoccurring.
One more thing, in the past 2 weeks I have also seen the LSASS subsystem shut a networked computer down, but the computer was not infected. Don't know what's going on there...[This message was edited by Ray Minich on 13 May 2004 at 09:05 AM.]
