We are attempting to setup a 5510 to use Radius pointing to a windows2008 server to authenticate remote VPN users. I have set this up with 2003 using IAS but 2008 replaces IAS with NPS. Attached is the meat and potatoes of the config and aaa server logs. It seems that the ASA is attempting to connect to the server but not receiving any response. I'm not sure if we would be better to leverage anyconnect ssl connection vs the Cisco VPN client, any suggestions would be appreicated.
