802.1x authentication with NPS on windows server 2008

I configured both on controller and radius server but I try to login by inserting username and password. There's warning that "Netwok policy server denined access to a user" and reason it 's "The client aould not be authenticated because the EAP type cannot be processed by server"

 

 

On labtop network authentication method is PEAP

Is PEAP configured in your network policy on the NPS side?

You need to create a server certificate for use with PEAP.

It can be issued by an internal CA as long as the client trusts it.
