All address' can be nslookup'd both forward and reverse. Nothing has
changed on either end. The server in question is part of a group of
servers that all back up just fine. All of the servers live in the same
physical location and all go through the same set of switches. None of
the others in the group are having troubles like this one is. If you see
the error I mentioned earlier when I try the backup from the server in
question does that mean the server in question cannot see the backup
server or is that response back from the NSR server that it doesn't know
how to communicate with the server in question? Thanks.

First thing, verify that reverse DNS works on both the client and
NetWorker server and that no one changed firewall rules on the client,
server, or anywhere in between them.
