How? The MAC address is assigned and registered by the manufacturer- it's unique to that device. Did someone replace that box? The address wouldn't change because control changed to RS-232 because the NIC isn't involved.
this happened to me once too. i had a receiver reserved in my router at home, I lost control of it one day. looked at the IP and it had changed to an open address on the network. compared the mac to what i had saved in the router and it had changed.
