Sounds like you've got the same client name on two different servers.
Each time they check in with TSM, they are updating their IP and
GUID.  Go check the dsm.opt on both those servers.

I've got a client that generates this 5-6 times a night:

It goes back and forth, causing great confusion to TSM.

I've asked the owner what he's doing and he asks me the same.
Anyone with an explanation?
