From some time now, our DC suddenly becomes unresponsive. Each time when this happens we had to perform a Hard reboot. However I found the following event occurring ever time before the server becomes unresponsive.
EVENT 260, stcvsm
"While re-activating on \Device\HarddiskVolume1, VDIFF has detected that previous boot session ended with a crash. VDIFF is terminated."
I have also attached the event log image file for your convenient.
Any help would be appreciated to solve this.
Server consists of:
Windows Server 2008 R2
ShadowProtect Server Edition 4.1
