At first glance, sounds like a networking problem. Copy/paste the full error messages here.

The session is rejected: There was a communications protocol error.

Explanation
An unexpected network message was received by the client. This could be caused by network problems or a programming error.

System action
TSM canceled the current operation.

User response
Verify that your communication path is functioning properly and try the operation again. If the problem persists, contact your TSM administrator for further assistance.

Confirms my earlier suspicions, sounds like a networking problem, not a problem with the TSM Client or the TSM Server, but rather with the communication between the two.
