The File Replication Service is unable to open the customer designated staging directory for replica set %1.  The path used for the staging directory is, 
    "%2" 
The customer designated root path for this replica set is: 
    "%3" 
 The service is unable to start replication on this replica set.  Among the possible errors to check are: 
  --  an invalid staging path, 
  --  a missing directory, 
  --  a missing disk volume, 
  --  a file system on the volume that does not support ACLs, 
  --  a sharing conflict on the staging directory with some other application. 
 
Correct the problem and the service will attempt to restart replication automatically at a later time.
