NPS Authenticating with Computer Certificate

Question

I have issued domain machines with workstations certificates.
I'm trying to setup up NAP 802.11x Wireless, where domain machines use their certificate to connect to a WPA-2 Enterprise protected SSID.

Can't seem to find out why i am getting the following error:
