I have an HP server Running Windows Server Advanced 2008 R2 and after running MS Updates I get a blue screen and a message about Fatal Error c00021a. I have tried sfc /scannow and it tells me that there is a repair currently in process when I havent started any repair process. I tried startrep.exe and it states that there are no problems detected. Anyone have an idea where to go from here?

1. Analyze dump file and see if you could find the root of problem. 2. Is this physical or virtual installation? If it is virtual on VMware, see the VMware forum. 3. What information (failure) is in WindowsUpdate.log file and ReportEvents.log?
