I am trying to change our wireless access points to use RADIUS. I have installed Network Policy Server on a server and pointed our wireless access points RADIUS settings to it.
I have allowed all Domain Users in the policy.
However when a client attempts to connect to the wireless network using the 'Use my Windows account' option (I have also tested manually entering
DOMAIN\user etc. with the same results) the client shows the error message
Unable to connect to this network
I have checked the Event Viewer on the server where Network Policy server is installed and this error message is generated each time a client tries to connect
Negotiation failed. No available EAP methods
Here is a screenshot of the properties of the policy.
