How can I limit DHCP addresses leasing to only give out addresses to PC's
that are in AD?

You can't really. DHCP is a basic system that works on broadcasts.

You could always configure the non-AD machines manually.

The basic problem is that DHCP doesn't know anything about AD. When you
start up a machine which is connected to the network (or plug in a machine
which is running), it sends a broadcast on the wire to find a DHCP server.
The DHCP server then replies with an offer. There is nothing sent about even
what sort of machine it is or what OS it is running. It is all very low
level stuff, so there is really no way to control what happens.

If you want to limit who can use your network or control what they can
or can't do, DHCP isn't the tool to use.
