OK, this must be simple, but we can't figure it out.

We have TDP for Oracle NT 2.2 on a WIN2K client.  .
We have been backing up successfully with it for a long time to an AIX TSM
server.

NOW we want to MOVE this client to a new Windows TSM server we are
implementing.

We have changed the TDP dsm.opt file to point to the new TSM server.

But when we run tdpoconf to reset the password on the client to the NEW TSM
server, tdpoconf returns "ANS1025E (RC137) session rejected:  Authentication
failure".

The connection is made to the NEW TSM server, and enough information gets
exchanged that the new server shows the client node as being TDP for Oracle
on NT.  But the message on the (new) server is ANR0424W, session rejected,
incorrect password.

SO we are getting the new TSM server, but can't get the password changed.
We've looked in the registry, and a new key has been created there with the
TSM servername of the new server.

SO WHAT ARE WE MISSING HERE?
Help!?!
