Decision Summary

Links between all sites should be defined through the use of one or more site links. If any sites are disconnected from the others, the Knowledge Consistency Checker (KCC) will generate an error message. The site links control the replication of the directory database between domain controllers in different sites and, if multiple paths are available, control which path is preferred.

The site link design can be changed. However, changing the site links may have an impact on the performance of directory changes until all updates converge.
