Preferred bridgehead servers have been selected to support intersite replication. However, none of these preferred bridgehead servers can replicate the directory partition.

Sample Event:

Preferred bridgehead servers have been selected to support intersite replication with the following site using the following transport. However, none of these preferred bridgehead servers can replicate the following directory partition.

Site: %1

Transport: %2

Directory partition: %3

Using Active Directory Sites and Services, do the following:

• Configure a domain controller that can support replication of this directory partition as a preferred bridgehead server for this transport by modifying the corresponding server.

• Verify that the corresponding Server objects have a network address for the transport. For example, domain controllers that replicate using the Simple Mail Transfer Protocol (SMTP) transport must have a mailAddress attribute. This attribute is normally configured automatically after the SMTP service is installed.

Until this is rectified, the Knowledge Consistency Checker (KCC) will consider all domain controllers in this site as possible bridgehead servers for this directory partition.
