Service Name: DFS

Executable Name: dfssvc.exe

Log On As: LocalSystem

Description: The Distributed File System (DFS) service manages logical volumes distributed across a local or wide area network. DFS is a single hierarchical file system, the contents of which are distributed across the network. DFS provides a logical tree structure for file system resources that may be anywhere on the network. Since the DFS tree is a single point of reference, regardless of the actual location of the underlying resources, you can access network resources based on a meaningful representation of the data. You no longer need to know and specify the actual physical location of files distributed across the network.

If the DFS service is stopped or disabled, users will be unable to access network data through the logical namespace and any attempt to configure a DFS root using the MMC DFS snap in will result in an RPC error. In order to for users to access the data, users will need to know the names of all the servers and shares in the namespace, and access each of these targets independently.

Available on: Windows Server 2003, Standard Edition; Windows Server 2003, Enterprise Edition; Windows Server 2003, Datacenter Edition and Windows Server 2003, Web Edition.
