Hi Start by checking 2 things: -Antivirus is looking at your NTDS Folder. -Disk performance is bad or disk is starting to crash or having other performance problems. -- I hope that the information above helps you Good Luck Jorge Silva MCSA Systems Administrator
hi Jorge, i had installad another DC and replicated AD information on this server all roles and AD objects. Then the first server was sutting down and off. Now AD is ok. I think it was a hw problem (like say you). thanks francesco
Glad to help -- I hope that the information above helps you Good Luck Jorge Silva MCSA Systems Administrator
Justin, assuming this is recurring error, other than the checking th eobvious (hardware problem), you might want to verify firmware/drivers for your disk controller and monitor disk performance to determine if these do not come into play... hth Marcin
