After Active Directory Connector is configured to synchronize
user and configuration directory information between Active
Directory and more than one Exchange 5.5 site, there are two
replication topologies replicating directory information to that
site. One is Active Directory Connector, which replicates
To avoid this duplicate replication, Exchange 2000 Knowledge Consistency Checker recognizes duplication and stops requesting replication across Directory Replication Connector. With Knowledge Consistency Checker, replication occurs only between Active Directory and the Exchange site through ADC. The Exchange 2000 server must act as the directory replication bridgehead server for the Exchange site to manage replication between sites.
