File Replication Service ( FRS ) is a Microsoft Windows Server service for distributing shared files and Group Policy Objects. This replaces the Lan Replication Lan (Windows NT) service, and has been partially replaced by the Distributed File System Replication. It is also known as NTFRS after the executable file name that runs the service.
One of the main uses of FRS is for the SYSVOL directory division. The share of the SYSVOL directory is very important in the Microsoft network as it is used to distribute files that support Group Policy and scripts to client computers on the network. Because Group Policy and scripts run every time a user enters the system, it's important to have reliability. Having multiple copies of the SYSVOL directory improves robustness and deploys workloads for this important service.
The SYSVOL directory can be accessed by using a network share to a server that has a copy of the SYSVOL directory (usually a Domain Controller) as shown below:
\\ server \ SYSVOL
Or by accessing it using a domain name:
\\ domain.com \ SYSVOL
The servers that work together to provide this service are called Replication Partners .
To control file replication:
- Use Active Directory Sites and Services from Administrative Tools .
- Select the Site container to view the list of sites.
- Extend the site you want to view. This will give you a list of servers on that site.
- Expand the server for viewing, right-click NTDS settings, and select Properties .
- Under the Connection tab, a list of replicated servers can be viewed.

DFS Replication
In Windows Server 2003 R2 and Windows Server 2008, DFS Replication is available as well as File Replication Service . DFS Replication is a state-based replication machine for file replication among DFS shares, which supports replication scheduling and bandwidth throttling. It uses Far Differential Compression to detect and replicate only changes to a file, rather than replicate the entire file, if changed. Windows Vista also includes a DFS Replication Service that is limited to the peer-to-peer DFS Replication service group. FRS is still used for SYSVOL replication, but optionally, DFS replication can be used instead of FRS replication for SYSVOL shares, and FRS stops. On top-level Windows Server 2008 domain controllers, SYSVOL replication is performed using DFS replication, by default even though NTFRS replication is also supported. In top-level Windows Server 2008/R2 domain controllers, SYSVOL replication is performed using DFS replication, and NTFRS replication is disabled at all.
