• 48 hours
• 15 minutes
• 60 minutes
• 5 minutes 

 

EXPLANATION

By default, the knowledge consistency checker (KCC) reviews and makes modifications to the Active Directory replication topology every 15 minutes. The KCC ensures propagation of data, either directly or transitively, by creating and deleting connection objects as needed. The KCC recognizes changes that occur in the environment and ensures that domain controllers are not orphaned in the replication topology.
