so you have name resolution Problem

1) confirm the what is the correct IP of the server by checking on the client network interface

2) are you using DNS or hosts file for name resolutions?

if DNS,

make sure DNS is resolving the correct name and IP, if not update the DNS entires.. ( DNS admin/OS admin task)

nslookup <clientname>

nslookup <client IP>

make sure both are giving the correct names..

if you are etc/hosts

update the etc/hosts file with correct IP address and client name

then test the ping communication.

if it looks fine

do bpclntcmd -clear_host_cache and then try for backup.

When ping gives you incorrect IP address, you need to check OS-level config.

You first of all need to determine if hostname lookup on NBU master and media servers is via hosts files or DNS.

If hosts files, you need to update it in all hosts files where this client is specified (master and media server(s).

If DNS, you need to check that DNS is indeed updated and that DNS cache has been flushed. Use nslookup to test forward and reverse lookup.

Once all of the above has been checked and confirmed, you need to flush NBU host cache with:
bpclntcmd -clear_host_cache 
on master and all media servers.

See:

PS: In future, please tell us what OS on the NBU master. 
I doubt that it is Windows 7....

Is this issue related to yesterday's post?
