We have three clients that were migrated to a different domain, and

the migration, I can't get these servers to backup. All three

Windows 2003 Standard Server, running the 7.2.2 client, and the
Networker
server is Solaris 8, running the 7.2.2 server. Other servers that
were
migrated haven't had any issues once DNS was cleaned up. Here's the
situation:
Backups from the server - it probes successfully and tells me what
drives
are on the server. But when it tries to back them up, it gives me an
error, Name resolution failed for the host with IP address:
x.x.x.x, then
Cannot open save session with the server.
Forward and reverse DNS lookup properly from the client to the
server, and
vice versa. I even put an entry in the hosts file on both the
client and
server.
Backups from the client - same name resolution error, then Cannot open
Backup session with the server.
I opened a case with EMC support, but after trying all her
suggestions, I
got nowhere. I've updated the ticket and havent' been called back,
so I'm
posting this to the listserv for help.
What does netstat say on the clients and server when a backup is
being attempted?
This is just a stab in the dark, but on the NetWorker server, go
into /nsr/tmp and grep the sg files for the old IP and/or hostname
for the clients and see if anything turns up. If you find an sg. file
containing the any of clients' old network information, that would be
cause for concern, especially if the last access date on that file is
fairly current. If you find such files, try shutting down all the
NetWorker processes on the server (nsr_shutdown) and then delete all
the files in /nsr/tmp but not the sec directory. Then either reboot
the server or start the NetWorker processes manually.
