Use this Knowledge Script to monitor the number of Knowledge Consistency Checker (KCC) connections to and from a domain controller. The KCC is a core Active Directory service that is responsible for generating the intersite and intrasite replication topology. This script raises an event if the number of inbound or outbound KCC connections exceeds the thresholds you set.
Significant changes in the number of replication partners indicates that something significant in Active Directory replication has failed, and KCC is automatically trying to recover. If the number of partners is too great, the replication window may close before replication can complete, causing replication to fail. NetIQ Corporation recommends that no domain controller ever serve more than 50 KCC connections because of the load generated by each partner.
