   • If it reports CIFS is disabled. Run:

     cifs enable

   • If it reports "CIFS is enabled and running.", then CIFS is already running, and no further action is necessary.
   • If it reports "CIFS is enabled but not running" or "CIFS is enabled, but winbindd is not running.", or any other status, then try restarting CIFS by running ' cifs disable' followed by 'cifs enable'.
