You Receive an "Event ID 1311" Message Every 15 Minutes in the Directory Services Event Log (819249)

SYMPTOMS

You may receive an "Event ID 1311" message similar to the following in the Directory Services event log every 15 minutes:Event Type: Error
Event Source: NTDS KCC
Event Category: Knowledge Consistency Checker
Event ID: 1311
Date: MM/DD/YYYY
Time: HH:MM:SS AM|PM
User: N/A
Computer: domain_controller_name

Description: The Knowledge Consistency Checker (KCC) has detected problems with the following directory partition.

CAUSE

In Windows 2000, the Knowledge Consistency Checker (KCC) uses the Intersite Messaging service to help it build the spanning tree topology for Microsoft Active Directory directory service replication. In a very small percentage of cases, Intersite Messaging may not complete building the hash table that it passes to the KCC. When the KCC uses this hash table in its calculations, this may generate the KCC logging event ID 1311 in the Directory Services event log.

This problem typically occurs in environments with large numbers of sites, domain controllers, and domains.
