Well if computer is not often used, then why are you worried about it? Yes I understand closed by mistake, but if you really want to keep the server from being closed by mistake create another account and use it and keep it locked, or lock the current account and use the new account for something else, thats my advice, but from what I can see, there is nothing I can or anyone else that I see of can do for you by putting a dedicated console in the tray.
