802.1x Wired

Wondering if anyone out there can point me to information on how to setup wired 802.1x with 2k3 IAS without using any kind of certificate. Cisco device is a 2960 ver 12.55SE and Windows XP sp3 with Correct Services Enabled. I have tried alot of commands on the switch to set this up but there are some problems I am hiting Example I plug the laptop into the port and run a debug on radius events and dot1x and I get all kinds of information about dot1x and then the port is block. I go into my IAS and there are no hits to the radius server. I cannot tell if the issuie is on the switch to server or the switch to Client.

I am attempting to config this with EAP with. MD5 Challenge
