I have a Exch 5.5 server in one site and Exch 2000 and Exch 5.5 servers in the other, connected by a site connector. Replication has stopped and I have error: 'Exception e0010002 has occurred with parameters 9 and 9 (internal ID 30503b2). Contact Microsoft Technical Support for assistance." I have restarted both directory services on Exch 5.5. I have also recreated the site connector. This hasn't worked at all. I have service pack 4 on Exch 5.5 servers. Please help on how I can resolve this replication problem.
