    Problems getting XP SP3 to Authenticate to NPS (Server 2008

    I have a Server 2008 R2 domain with windows xp sp3 clients. The Server 2008 R2 is a DC, Certificate Authority and NAP Server. I have cisco switches setup correctly to use 802.1x as I used to have a server 2003 domain with IAS and everything was fine.

    In NPS I have created a wired policy to put clients on to Vlan 2. In group policy, there are wired settings for clients to use PEAP and the Certificate to connect.

    The clients use machine credential. When I try and connect the client to the network..... I get Authentication Failed and in the Event Viewer on the NPS server I get:

    Having much the same problem here.

    2003 to 2008 and all the clients seem to be stuck on verifying. We did at one point have it working on our phones.
