Wireless on XP clients, PEAP setting not applying from Group Policy GPO

Hi

I have a problem as follows.

I have set up some Cisco Aironet 1042 APs. These use RADIUS to authenticate the clients against our Active Directory using EAP.

Our Windows 7 laptops will connect and authenticate straight away with no problem.

By default when the Windows XP SP3 clients try to connect they display an error "Windows was unable to find a certificate to log you on to the network xxxxx". This can be resolved by setting the EAP type to 'PEAP' instead of 'Use smart card or other certificate'.

I have created a GPO for the XP clients to pre-configure the SSID so that the correct settings should be available, however the 'EAP Type Protected PEAP (PEAP)' setting does not get set on the client. All the other GPO settings do get set correctly.

Does anyone know why this setting is not being applied by the GPO?

Thanks in advance.

In the Computer Configuration/Windows Settings/Security Settings/Wireless Network, I have created a GPO called 'Wifi'. In the Preferred Networks section I've added my SSID, and in the IEEE 802.1x section I've set the EAP type to 'Protected EAP (PEAP)'

Thanks

I have resolved this issue. You need to extend the Active Directory schema to allow 802.11 PEAP authentication, Windows 2003 domain controllers do not support this by out of the box. See the following TechNet page which explains how to do it. It takes approximately minutes.
