Has anyone had any success using 802.1x on a Cisco Catalyst 3550 series switch, with the built in client on XP (sp2)? We've been trying to get it working in our lab, and haven't been successful. As far as Cisco is concerned everything is configured correctly, because using a *nix laptop we were able to authenticate on the switch.
I'm using windows 2k3 IAS for the authentication part, and the 3550 is configured with 802.1x as per this page's instructions:
I just wanted to see if there are any success stories out there, since we've been knocking our heads on this one for close to a month now.
