Authentication Problem and Downlevel Server version

Hello everybody

I have a TSM client (version 4.2.1) running on AIX 4.3.3. I have two errors
situation (distinct, I think) on this client.

Situation 1:

When I make a "q node" I receive the following message:
I already change the node name and re-install the client with a new name.

tsm> q node
