How to optimize Active Directory replication in a large network
The Knowledge Consistency Checker (KCC) dynamically adjusts the data replication topology of your network when domain controllers are added to or removed from the network, when a domain controller is unavailable, or when the data replication schedules are changed.
The tasks of the KCC are:
|•||Based on the network topology described by Active Directory objects, the KCC creates connection objects which are used to define inbound and outbound replication to domain controllers:
|•||Convert the KCC-defined and administrator-defined Microsoft Windows NT Directory Service Connection (ntdsConnection) objects into a configuration understood by the Directory Service (DS) replication engine.|
By default, each of these tasks is executed every 15 minutes. For more information about the KCC, please see the Active Directory Replication chapter in the Windows 2000 Resource Kit.
