Do the right click and run as admin, and then all functions work as normal. I think it's a security feature to prevent batch files and other malicious programs from executing code as an administrator, even if you are logged in as an admin. Kind of annoying in a way, but also more secure.
Thanks for the advice, I will try it sometime this week when I feel like reconnecting the other computer.
