Default Behavior

DFS Namespace Client Driver is a file system driver. In Windows 10 it is starting at Kernel initialization. If DFS Namespace Client Driver fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the Dfsc service has failed to start due to the error.


DFS Namespace Client Driver cannot be started under any conditions, if the Mup service is disabled.
