PEAP failure

I have a 4404 controller with a Microsoft IAS server running radius. I can connect to the WLAN when I have no encryption. When I turn on WPA2 with AES and try to connect it fails. I ran the debug dot1x events enable and here is the output. There is one line that states AAA Error no Server.

Mon Jul 7 18:29:58 2008: 00:13:02:14:c7:b3 Sending EAP-Request/Identity to mobile 00:13:02:14:c7:b3 (EAP Id 1)

Mon Jul 7 18:29:59 2008: 00:13:02:14:c7:b3 Station 00:13:02:14:c7:b3 setting dot1x reauth timeout = 0

Mon Jul 7 18:29:59 2008: 00:13:02:14:c7:b3 Stopping reauth timeout for 00:13:02:14:c7:b3

I can ping the server from the 4404, have re-entered the shared secret several times. I even deleted and re-added the radius information with no luck.

Does anyone have any ideas?

Re: PEAP failure

Send a 'show wlan summary' and a 'show wlan ' for the ssid that you are having this issue with.

Re: PEAP failure

Take a look at the event viewer in the IAS box to see if it even receiving anything from the WLC. Also you have the IAS set to Radius Standard when you created the Radius Client?

Re: PEAP failure

This wlan looks like it is setup correcdtly for 802.1x and wpa2/AES. What errors do you see in the IAS server event viewer.

Re: PEAP failure

Nothing is showing up in the event viewever. Can anyone direct me to a guide on setting up IAS 2003 to work with the WLC?

Thanx

Re: PEAP failure

This is the guide we used for configuring IAS.

You should atleast see the WLC hitting the IAS server in the IAS server logs. Are you looking in the IAS logs or just the system event viewer?
