Win2k Server Add a Machine (instead of a User) to a Group

Is there any way to add a certain machine (by machine name, IP address, MAC ID, anything) to a specific Group? I know this seems like a strange request, but we’re working with third-party software that can only assign profiles by Windows Users or Groups. I have one machine that I want to use the same profile, regardless of what User is logged in. So if I could create a group, add that MACHINE to it, and then set up a profile for that group, my problems would be solved.
