Huh? How can a hard-coded mac address be changed? It's burned into the NIC controller chip, and every single network-attached device has a unique MAC address. I've never heard of being able to change them.

If this were my situation, and if I were in a windows enviorment, I would lock down the computers using something like Fortres (which I actually use, by the way). Just lock down the desktop and users can't change the ip.
