11.22.3 Discussion

Hopefully you will not need to create connection objects manually. Creating and maintaining connection objects is the job of the KCC. It can be a lot of work to keep your connection objects up to date by yourself, especially if you have a large topology. The KCC uses complex algorithms to determine the best partners for a domain controller to replicate with. The Windows 2000 KCC had problems generating very large topologies, but the Windows Server 2003 version is significantly better.

It is sometimes necessary to create connections manually if you find a replication problem and need to get replication going again between one or more sites. By creating a connection and forcing replication to occur over that connection, you can get servers back in sync quickly.
