PEAP is not working on the client.

Hi,

Here is my setup :

AP - Cisco AP 350 Series
Radius - IAS, Windows Server 2003 with SP1
Client - Windows XP Pro

The AP option under the security for EAP, MAC and USER authentication are
checked.

The IAS server have a server certificate installed.under the "Remote Access
Policies" -> Edit Profile -> Authentication -> EAP Methods -> EAP Types and
under the Protected EAP, I can see the server certificate. Fast reconnect is
enabled.

The method of authentication that the client used is only "Secured password
(EAP-MSCHAP v2)". Fast Reconnect is enabled. No certificate.

The issue that I have is that the client did not get the logon screen and
the wireless connection will failed. Why did the client didn't prompt for
the logon screen ?

Help..

Thank you.

Rgrds,
Zul
