My son lives four hours away. I'm trying to do phone support for him on his PC (XP pro), which won't connect to the internet. In asking him to try various things and report what (if anything) happened we discovered that ipconfig /all is reporting his MAC address as 00-11-22-33-44-55. Nuh-huh! Fuller violently shakes head until pea brain rattles.

I built this PC myself back around Christmas and documented it from soup to nuts. That is NOT NOT NOT it's true MAC address. Can anyone suggest where it might be coming from?
I know of two ways to spoof a MAC address in XP, one done using the NIC's properties (Advanced/Network Address/Value) and the other being a registry hack. The NIC's properties have not been diddled with; and I had him search in regedit for the string that's being reported as the spurious MAC address. Not found. Where else might a phony MAC address be imposed on the system?
Oh, google. It's no help because so many people use that string to describe the form of a MAC address ("Look for a number that looks like 00-11-22-33-44-55.")
