File Replication Service (FRS) supports synchronizing folders with file servers that use FRS instead of the newer DFS Replication service. To enable a server to synchronize folders with servers that use FRS with the Windows Server 2003 or Windows 2000 implementations of Distributed File System, install File Replication Service. To enable the latest and most efficient replication technology, install DFS Replication instead.
