Environment



Netbackup version 7.1.0.3

Win 2008 R2

Exchange 2010


Cause



Client for NFS was running with domain admin privillages.

The following caused the nbfsd mount operation failures.

 


Solution



It is recommended to run client for NFS on windows 2003 R2 and windows 2008 servers with default Network service account.

Client for NFS does not require domain adminstrator account  for GRT specific tasks
