Is there any way to prevent a specific computer from obtaining a DCHP address from my DHCP server? I need a solution for both NT 4.0 server as well as 2003 server. I want to do this from the server side rather than the client side (very important). Shouldn't I be able to restict access from that specific MAC address? If so what steps need to be taken to achieve this? Also I want to do this without creating a new scope or superscope if possible.
