We are using the mac address to identify the client machines on a network.
However now that they are using some Windows 7 terminals, and they are using some wireless device, it seems that those machines do not get a mac address. At least our code does not return any value.
What is the second best way to identify a computer, the only important thing is that this computer must generate the same key each time and it must be unique.
