I was unable to get Winsock to deliver the MAC address to me but it does have the IP address. I got your message while I was reading Christof's doc's and might play with that some (although it is beyond my current understanding).

Maybe someone else has the time to develop the necessary classes for you.

Thanks Ed, maybe this winter when things settle down I will look some more at Christof's stucture class. I use third party libraries when I have to but there is nothing like native foxpro code...
