I don't know if this will help but I came across a link where they use either NetBIOS or RPC protocols to query for the MAC address.

Another place had this code:

>#include
>#include

>main(){
> UUID ID;
>
> UuidCreate(&ID);
> printf("%02X:%02X:%02X:%02X:%02X:%02X\n",
> ID.Data4[2],
> ID.Data4[3],
> ID.Data4[4],
> ID.Data4[5],
> ID.Data4[6],
> ID.Data4[7]
> );
>}

Because apparently the UUID uses the MAC address.

I don't know if any of this helps, but I'd thought I'd atleast mention them.
