Thanks - I know I can do that. What I'm trying to do is to identify Windows machines. I can see all the MAC codes, but the Apple machines allow me to set the Client ID with an easy descriptor, such as "Pete's MacBook". Then, on the DHCP list I see the easy descriptor. I'm trying to understand how to set the Client ID on Windows machines, so I can also use and see an easy descriptor.
If you can answer that, I'd be very grateful!
