Description: Enables files to be automatically copied and maintained simultaneously on multiple servers. File Replication Service (FRS) is the automatic file replication service in Windows 2000 and the Windows Server 2003 family and its function is to replicate the volume (Sysvol) on all domain controllers. In addition, it can be configured to replicate files among alternate targets associated with the fault-tolerant Distributed File System (DFS).
This service that provides multimaster file replication for designated directory trees between designated servers running Windows 2000 or Windows Server 2003. The designated directory trees must be on disk partitions formatted with the version of NTFS used within the Windows Server 2003 family. FRS is used by the Distributed File System (DFS) to automatically synchronize content between assigned replicas and by Active Directory to automatically synchronize content of the system volume information across domain controllers.
If this service is stopped or disabled, file replication will not occur and server data will not be synchronized. Stopping the File Replication service on a domain controller may seriously impair a domain controllers ability to function.
For more information about FRS, see "File Replication Service" in the Windows Server Distributed Services Guide.
