Ntds.dit corrupted
Hi, I have a domain with multiple DCs, the primary DC hosting all the FSMO rolls, has crashed after a power failure. I receive a BSOD with the following error: “STOP: c00002e2 Directory Services could not start because of the following error: A device attached to the system is not functioning. I found some entries in a forum that discussed mixed up drive letters, my system partition lost the letter C:\ for some reason, thus I switched that back. I then restarted and booted into DSRM. I then made a backup of the c:\windows\ntds\ directory and continued to run the following command to check the integrity of the database: esentutl /g c:\windows\ntds\ntds.dit The scan completes and I received an error message that the database is corrupted. "Operation terminated with error -1206 (JET_errDatabaseCorrupted, Non database file or corrupted db) after 7.16 seconds. I then followed a procedure on a forum to check the DB with NTDSUTIL I opened NTDSUTIL, connected to the active instance, typed file, typed info and receive no errors. But when I run Semantic Database Analysis without the fixup option, I received loads of errors. I then ran the analysis with the fixup option and received a lot of errors again with the below as the result: Error: Inconsistent SD refcounts detected. I then did a soft recovery of the DB and got the message that the recovery was successful. I then ran the Semantic Analysis again to test the recovery, but I receive a lot of errors again stating: *** Errer: JetDelte/Update failed with [ Jet Error -344]. I then read that a defrag must be done on the DB, I then ran an offline defrag and received the below: operation terminated with error -327(JET_errBadPageLink,database corrupted) Unfortunately there are not system backups for the server. Any advice will be appreciated. Regards,
