The File Replication Service is unable to open (or create) the pre-install directory under the customer designated replica tree directory for replica set %1.  The path used for the pre-install 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 root path, 
  --  a missing directory, 
  --  a missing disk volume, 
  --  a file system on the volume that does not support NTFS 5.0 
  --  a sharing conflict on the pre-install directory with some other application. 
 
Correct the problem and the service will attempt to restart replication automatically at a later time.
