I keep getting these messages on my Linux TSM server, which is on a
heavily firewalled network.

Yes, there are some issues with the DNS names for these boxes.

How do I stop these errors / the TSM server from constantly trying to do
DNS lookups ?  Especially when it attempts this 100's of times, each
generating an error message in my daily logs.
