Is there a way in XP that I can know what the mac address
is of the computer that is causing the IP conflict. The
network we use is static IP or not DHCP. So this person
is doing it on purpose and changing to other peoples
IP's. How can I find there mac address when they are
doing this so I can tell the other people on the network
how to record it for me.

Thanks Neal
