Actvie Directory Database Corruption >Event ID 467 > Index of table datatable is corrupted

[PatrModer]

Hi, we are running a Windows 2003 SBS with Active Directory. Since past four days I don’t know what went wrong suddenly our Active Directory database started Corruption Error logs in Event Viewer. It says

“Event ID = 467

Category : Database Corruption
Event ID : 467

Description :
NTDS [696] NTDSA : Index INDEX_00020078 of table datatable is corrupted [0]”

Can somebody please tell me what is the problem and how can I fix it? Many thanks.

Ok, just try out the following steps and see what happenes:

• Boot into Active Directory Restore Mode
• Run ntdsutil.exe from a command prompt
• Click File > integrity

Apart from this, do an offline defrag (you will find this option in ntdsutil). That should repair the index. Let me know the results.

Thank you very much for the help Domi.nick. I ran the offline defrag on Active directory database and that fixed the problem.

Thank you very much.

For those who are having this issue and event ID 476 an offline defrag fixed our active directory issues when ndtsutil recover and integrity checks did not work.
