Simple definition
The Knowledge Consistency Checker automatically manages Active Directory replication connection topology.
Purpose and use
The KCC, Knowledge Consistency Checker, builds and adjusts logical Active Directory replication connections.
How does it work?
It runs on domain controllers and uses sites, partitions and available topology information to generate appropriate connections.
Example and verification
During a fault, inspect connections, sites, links and replication events before adding permanent manual relationships.
Points to watch
The KCC does not create physical network connectivity or repair broken DNS resolution or filtering.
In short
Calculated topology must match hosted partitions and actual communication paths between controllers.
