4.4 Configuring SMTP Replication

As an aid for implementers who are attempting to set up and test the DRS Protocol Extensions for SMTP, this section provides an example of how to configure SMTP replication between two DCs. In the example, replication occurs between two DCs that are in the same forest, but in two different sites and domains. Only the configuration and schema partitions (which are common to all domains in the forest) are replicated via SMTP replication.

The relevant information with respect to the two DCs is as follows:

  • DC1

    • Domain controller name: DC1

    • Domain: dc=corp,dc=contoso,dc=com

    • Site: firstsite

  • DC3

    • Domain controller name: DC3

    • Domain: dc=remote,dc=corp,dc=contoso,dc=com

    • Site: remotesite

With the DCs configured as described here, create a new site link with SMTP as the transport. Place both DCs in that site link. Be sure that any other site links that also contain the two DCs have a cost greater than that of the SMTP site link.
