Actvie Directory Database Corruption >Event ID 467 > Index of table datatable is corrupted
Sam
Dear All,
We are asking for help with our Windows 2003 Small Business Server with
Active Directory database problem.
We have an Active Directory Database Corruption Error coming up as Event ID
= 467 in the Event Viewer Log :
Category : Database Corruption
Event ID : 467
Description :
NTDS [696] NTDSA : Index INDEX_00020078 of table datatable is corrupted [0]
-----------------------------------------
We have tried the following method but it did not work :
1) Boot into Active Directory Restore Mode
2) Run ntdsutil.exe from a command prompt
3) > File > integrity
4) After integrity check, the screens shows that :
Database is CORRUPTED.
Operation terminated with error -1206 ( JET_errDatabaseCorrupted, Non
database file or corrupted db)
Spawned Process Exit code 0xfffffb4a(-1206)
5) We tried to run " ntdsutil > file > recover "
The screen said :
Operation completed successfully in 1.2 seconds.
Spawned Process Exit code 0x0(0)
6) When we run 'integrity' again, result is still the same as above in 4).
7) We tried to run "repair" (as recommended by some literature), but NO such
a command exists under the menu inside : ntdsutil > file
8) We then run > ntdsutil > semantic database analysis, with screen as
follows:
> semantic checker : verbose on
Verbose mode enabled
semantic checker:go
Fixup mode is turned off
Opening database [Current] ... Done
Getting record count... 7333 records
Getting security descriptor count... 163 security descriptors
Writing summary into log file dsdit.dmp.0
SDs scanned: 7333
Processing records..
Error : Inconsistent SD refcounts detected !!!
Done.
-------------------------------------------------
We would like to get help from all the experts whether there are any ways to
fix the Active Directory database corruption problem.
Also we are wondering why the 'repair' option inside ntdsutil.exe does not
seems to exist in out Windows 2003 Small Business server. Could anyone give
some insight into the use of 'repair' command ?
Many Thanks for everyone who could send helps of any kind.
Best regards
Sam Tsui

For those who are having this issue and event ID 476 an offline defrag
http://support.microsoft.com/?kbid=232122 fixed our active directory
issues when ndtsutil recover and integrity checks did not work. ...be
advised running the offline defrag is very dangerous if you don't have
another domain controller in your domain. We are still not sure if the
derag fixed the corruption, or if deleting the log files which were
rolling forward entering corrupt data fixed our issue, but either way it
fixed the issue.
