Active Directory Recovery Guide

I’ve been having numerous errors in the event log appearing on one of my servers from the ESENT service:

Event Type: Error
Event Source: ESENT
Event Category: Database Corruption
Event ID: 467
Date: 18/05/2007
Time: 09:33:06
User: N/A
Computer: SERVER123
ntfrs (5660) Index GChangeOrderGuid of table OUTLOGTable00002 is corrupted (0).

For more information, see Help and Support Center at

These errors are appearing regularly, and contain various tables with problems.

After scouring and the Microsoft support site – I eventually found a very useful Powerpoint presentation that outlines various methods of recovering poorly or corrupt active directory databases.

Although not a specific answer to the problem, it does provide useful guidelines in the best practices for repairing or reinstalling and domain controller, as well as some useful advice such as carrying out a metadata cleanup.

I’ll be following the guide to try and resolve the database errors on this server, and hopefully it will work out nicely.
