Also, since I was able to connect from my laptop with no problem, it led me to believe it was something wrong with my desktop.
After about 30 minutes of fiddling around with various settings, I was able to figure out what the problem was.
Screenshots are taken from Professional version thus may slightly differ from other versions (e.g.
Home Edition, etc.): You have now succesfully configured Windows XP to connect to eduroam network.
By default, XP will re-authenticate with the user credential after the user logs-on (there is no way to do computer-only with XP, I believe).
Click on the Authentication tab and now uncheck the Enable IEEE 802.1x authentication for this network box.
If the box was checked, then that was why you were getting the “unable to find a certificate to log you on to the network” message because Windows is looking for one, but your wireless router is not setup for certificate security. Once I unchecked that box and tried to reconnect to the wireless network, everything worked fine!
I cannot get WPA2 enterprise to work on my network. Windows Domain, using IAS and its own CA Linksys WAP200 Access Point I setup the AP to use WPA2-Enterprise Mixed using RADIUS I setup and registered IAS on the domain controller.
I added the AP as a client with and have tried using both RADIUS Standard and Cisco as the RADIUS type.
