I've been having some trouble setting up NetWorker in our Exchange 2013 environment running on Windows Server 2012 R2.  We are using a DD2500 for backup, then replicating to another DD2500 off-site.

After installing NetWorker and NMM 3.0 on all of the servers in the DAG, I was able to add the DAG which consists of 4 exchange servers as clients to NetWorker Admistrator.  After going through all of the steps in the setup guide and checking my storage node config, data domain device, storage pools, groups, etc., I am receiving an error 101847:nsrsnap_save:Cannot backup: Mount Host name not specified.  Please see attached screen shot.

Also, for one of our file servers which I just need regular backups down for, it is giving me a different error.  This particular server is running Windows 2008 R2 and have installed both NetWorker as well as NMM 3.0.  Here is that screen shot when I try to perform a backup -

I have tried turning client direct off and back on.  Have made sure the storage name is set to "networker.ulthera.local" like it should be.  Not sure where to go next to troubleshoot.  Any help is appreciated.
