Yoda, I don't want to sound condescending so please excuse me if it does. It appears by some of the questions you're asking that you would be GREATLY benefited by taking some time and reading at least the TSM Redbooks, and some of the Admin guide. I would recommend the deployment Guide Redbook, and the Technical guide.
To be specific on the question below, you need to login to the TSM server console and run "halt" after verifying that there are no processes, and no tapes mounted. Then make sure all TSM Services are stopped. I would also imagine that you would need to be logged into the Windows Server as Administrator or equivalent.
