Dell Latitude - Ethernet MAC address change???

One of our Dell Latitude D630 laptops was transferred to a new user, and before I gave it to the new user, I wanted to re-install Windows on it and give the new user a "clean" installed system.  The problem is, we have a software tool that uses the MAC address of the Ethernet adapter to verify a license file.  I have never heard of or seen a MAC address change on an Ethernet adapter before, but after the windows install, it appears the MAC address HAS changed!?  Is this normal?  Maybe because it's a Dell laptop, the Ethernet adpater is some sort of virtual adapter, and there isn't a mac address burned into it?

I am positive it's the same adapter.  There is a wireless card and Local Area Connection.  These are the only two adapters, and nothing physically has changed...just the windows re-install.

All device drivers are installed correctly - no errors (yellow icon)

I have done ipconfig/all and thought many times and checked each device mac address...none match the "old" address that was there a few days ago on the NIC.

Not sure what happened, but I was just looking to make sure that there wasn't something I was missing by asking this question.  I thought there really was no way of changing the mac address (other than some driver tweaking), and that about answers my question.  Thanks!
