Mark,
are you using the clients ip address as its nodename?
Now when you change your TSM servers ip address this does not affect the
clients, except your TSM servers client...
To fix this problem you could
use more symbolic nodenames that do not change when ip addresses change
rename your TSM servers nodename
        rename node <oldname> <newname>

Good luck,
regards,
Michael
