Try pinging the affected ip address, and then running arp. It'll at least tell you one of the mac addresses. Then remove that device temporarily, ping it again and run arp again. Should tell you the mac address of the second device. In the future consider setting your DHCP server to dish out even the static addresses. You basically say 'this mac address gets this ip address'. One configuration in one place, instead of having to maintain the information on each computer. If your router's dhcp server doesn't have this capability exposed to the web ui, it wouldn't be difficult to set up one of your Linux servers with this responsibility. Just an idea. Central administration, even for small networks, is better than spread-out administration.
