Encyrpting Win2k Communication

Well, I'm thinking about redesigning my network at home. Part of that redesign includes encrypting all traffic that travels through my wireless network.
Basically, I want anyone who connects to my AP to be authenticated by my 2k DC before they are able to browse the internet. Since, I'm restricting the people who can use my AP, I figure that I should add a little more security to my 802.11b communication. I'm not talking that childish WEP encryption, but solid PGP type stuff. I just don't know if 2k can do this natively or if I have to "acquire" more software to accomplish this task.
Any input would be truly appreciated.

hmm... here is a backwoods way of doing it....

Setup the DC to route traffic, the "wireless ip" in on a encrypted VPN network.... all client connent via VPN over the wireless link to the DC and the DC has a second NIC on a seprate subnet to the internet... then allow only VPN traffic to route out.

well you get the picture....

Interesting. I had not even thought of using a VPN to encrypt traffic over 802.11b. I knew I posted this here for a reason.

yea... I had to do it for a Government network i helped setup off base. :)

the VPN i used was 168bit encrypted and no hacker is gonning to get in there, on the local computer or the link back to the main site. very secure. (when done right)

If you need more help, let me know. (we used real router for the traffic routing, but you can do it on the DC or any linux box setup as a router)

Yeah, I know a dedicated router would be the best way, but I'm trying to keep my network 1.simple and 2.cheap. If I can do it with the equipment I have, then so be it. I may be back asking for more help with configuring.
