Greetings from Software Guru Associates: I know methods that allows user to query the MAC address in a NIC card at runtime. You need to do some research in DDK for NIC MAC. All the information about the MAC address that tied into NIC card are locate in Registry.

A few weeks ago, I was looking for the same thing. In the end, I decided to settle for the approach of using Win32 IPHlpAPI functions to pair the IP addresses and MAC addresses, and then used the IP address information from pcap_findalldevs() to pair up the MAC address returned from M$ to the adapter information returned from WinPcap... not the most elegant solution, but it works reliably.
