Explicit bridgeheads to support inter-site replication to and from site CN=<cn name>,CN=Sites,CN=Configuration,DC=<dc name>,DC=<dc name>,DC=<dc name>, over transport CN=IP,CN=Inter-Site Transports,CN=Sites,CN=Configuration,DC=<dc name>,DC=<dc name>,DC=<dc name>, have been selected, but none of these servers can replicate the partition DC=<dc name>,DC=<dc name>,DC=<dc name>.
Please use the Active Directory Sites and Services snap-in to do the following:
1. Configure servers that can support replication of the given partition as preferred bridgeheads for this transport. You can do this by modifying the corresponding server objects.
2. Ensure the server objects have an address for this transport. For example, servers performing replication over the SMTP transport must have a mailAddress attribute. This attribute is normally configured automatically after the IIS/SMTP service is installed.
In the meantime the KCC will consider all servers in this site as possible bridgeheads for this partition.
