Legacy Distinguished Name of SMTP Connector Not Replicating Correctly (309752)

MORE INFORMATION

Specifically, an Exchange 2000 Server in the Exchange 2000 administrative group generates a gateway address routing table for its own administrative group. This routing table uses the Active Directory listing of the SMTP Connector legacy DN. The Exchange 2000 Server gateway address routing table is passed to the Exchange 5.5 Site, and Exchange 5.5 Server uses that routing table to generate its own Exchange 5.5 gateway address routing table.

However, in a pure Exchange 2000 Server administrative group, an ADC does not back-replicate Exchange Server 5.5 DNs to legacy DNs for an SMTP Connector. If the Exchange 5.5 Site has a routing ID master server that runs Exchange 5.5, the routing ID server looks for an SMTP Connector DN that matches the DN that is listed in the Exchange 5.5 routing table--that is, the routing ID server looks for the Exchange 2000 legacy DN that the Active Directory provided. Because the Exchange 2000 Server legacy DN is not replicated back from the AD to the Exchange 5.5 Server directory, the routing server identifies a mismatch and does not add the SMTP Connector to its Exchange 5.5 gateway address routing table.

Furthermore, the SMTP Connector is not added to the routing table of any administrative group in which Exchange Server 5.5 is the routing ID server.

If the routing ID server in the Exchange Server 5.5 Site is an Exchange 2000 Server, the gateway address routing table is successfully populated with the SMTP Connector.
