 * cm_conn.c: assume that if all of the servers for a cell are DOWN
   that there is NOSUCHVOLUME.  We can't return TIMEDOUT because 
   this assumes there is a server which is up and the windows shell
   will in turn continue to try to reach it for several minutes on
   each refresh.  Of course, each refresh occurs more frequently 
   than the timeouts.

   We can't return ALLOFFLINE because that in turn results in 
   an attempt to cm_ForceUpdateVolume() will a NULL (cm_fid_t *).
   That in turn causes a null reference and a crash.  

 * cm_volume.c: place a check in cm_ForceUpdateVolume() to return
   without performing its job if there is no (cm_fid_t *) value.
   Unfortunately, this in a ALLOFFLINE situation places the 
   service into an infinite loop.  

   Question: why is cm_ForceUpdateVolume() ever being called with
   a NULL parameter for the (cm_fid_t *)?

 * cm_smb.c: change the NTStatus for CM_ERROR_NOIPC to Remote
   Resources instead of Access Denied.  

 * cm_buf.c: add a debugging statement
