The TSM server is not accepting administrative sessions on the client port. You must use the port number designated for administrative sessions.
The TSM server is configured to not allow administrative sessions on the client TCP/IP port. A different port number has been designated for use by administrative sessions.
The administrative session is not established.
Use the TCPADMINPORT client option to specify the TCP/IP port number that the TSM server uses for administrative sessions. See your TSM server administrator if you do not know the correct port number.
