2008 Server & Radius

I retired our windows 2003 server that was also acting as a radius server
for our firebox VPN.
I installed the Network Access and Policy role on 2008 server to replicate
what was being done on our 2003 server.
I went through the few steps to configure it telling it to grant to the
appropriate group.

When I try to connect over the VPN it hangs at verifying username/password.
I see the attempt on the firewall/vpn appliance, but I dont see any events
in the log on the server. This wasnt that complicated.

Any ideas on what im missing?

I set the secrete password the same on the vpn and the config on windows
2008.

thanks,
