RDM Auto Start wihout being logged in on server.

I running a Windows Server 2003 fully up to date. I have RDM+ a remote desktop software http://www.rdmplus.com/ installed on the computer. So I can remotely access the server from anywhere off my blackberry. The problem is I do not want to have to be logged-in in order for the program to be running.

How can I accomplish this. Do I need to make it a service or scheduled task? Or am I way off

Thanks for the help
