ethernet address

Hi,
I'm trying to install software whose licensing depends on the Host ID (ethernet card address, in Xp you typed ipconfig /all). Vista can't even find the card in my system (even though it's listed and working properly in the Device Manager); also this PC works fine with Internet and even ICS; I can use the other PC on my network (Local and Internet).
What do I do to make my ethernet card visible to the applications?

Hello,
I typed ipconfig /all on my system and it gave me the info. I also use ICS and my actual network card was listed before the Tunnel adapter.
