I done a fresh install of Server 2008 last week (on a HP Prolian ML350) and it's been running fine up until this morning when users reported the network was down.
Locally on server I could move the mouse but that was it, I had to do a hard reset. It booted up fine. I then installed one critical MS patch from automatic updates (I did not get the number) and installed the two following hotfixes: 961775 and 959816. I could not find aything in the events as to why it froze. There was an 'unknown device' in device manager, I disabled it. I then rebooted, it shut down gracefully but now it will not start up!
It gets to the scrolly bar, loading devices, In safe mode it stops at crcdisk.sys.
I have done some reseach however the majority of crcsisk.sys issues occur during the first insttallation and are caused by RAID or SATA/SCSI drivers.
