N00b question: how do you register MAC addresses? Aren't they hardwired in the NIC?
The IEEE assigns MAC addresses to hardware makers (actually large blocks of addresses), you can use a tool on their site to see who made the device.

»standards.ieee.org/regauth/oui/index.shtml
Use the "Search the public OUI listing" box and enter the fist 6 hex digits of the MAC address.

It's also quite trivial to spoof a MAC (windows will actually check the registry for a MAC address of the network card, before using the card's built in one so its just a registry key change)

but as it has been said earlier it this thread, since it is only Deny's showing, i wouldn't be concerned.
