Symptoms

Consider the following scenario:
  • You define a tuple index for an Active Directory attribute in a Windows Server 2008 R2 domain or a LDS instance.
  • The attribute has multiple values.
In this scenario, queries perform slowly, or other failures occur in applications or services that rely on the tuple index. Additionally, the Active Directory database engine ESE reports tuple index corruption, and the following event is logged to the Directory Service log on one domain controller in the domain:

Event Type: Error
Event Source: NTDS ISAM
Event Category: Database Corruption
Event ID: 467
Date: <date & time>
User: N/A
Computer: <computer name>
Description:NTDS (436) NTDSA: Index <name> of table datatable is corrupted (0).


Cause

This issue occurs because the Active Directory database engine manages the tuple index for the attribute incorrectly.

Resolution

To resolve this issue, install the following hotfix package on all domain controllers of the forest. After you install the following hotfix package on all domain controllers or LDS instances, recover the database from the corrupted indexes.

To recover the database from the corrupted indexes, use one of the following three methods:
  • Perform an offline database defragmentation. After you perform an offline database defragmentation, all index data is removed from the database, and then the indexes are rebuilt automatically when you restart the domain controller or LDS instance.

    For more information about performing an offline database defragmentation, click the following article number to view the article in the Microsoft Knowledge Base:
    232122 Performing offline defragmentation of the Active Directory database
  • Remove and reinstall the affected domain controllers.
    Important For a domain database, do not use Install From Media (IFM) because the backup database may include the corrupted indexes.
  • If you know which attributes are affected, remove the index from these attributes, and then add the index back to them.
