Thank you all very much.
First, the Win32_NetworkAdapter idea is great. Will that show all network adapters?
I tried running it once before and it gave me several 00-00-00 type mac addresses and mine...

Secondly, if I could do it totally SQL, I would, but I have no idea about SQL...

The problem that I really want to work out first is how to use this code and connect to SQL DB. Maybe it needs to be pure SQL?
