The DFS Namespace Client Driver service is a file system driver. In Windows 8 it is being loaded and initialized at Kernel initialization. If DFS Namespace Client Driver fails to start, the error details are added to Windows 8 error log. When the operating system startup is complete, the user is being notified that the Dfsc service hasn't been started.


DFS Namespace Client Driver can't start, if the Mup service is disabled or not available.
