NPS and Domain Controller Communication
Applies To: Windows Server 2008
Network Policy Server (NPS) contacts domain controllers to perform authentication and authorization for connection requests received from configured RADIUS clients. If NPS cannot contact domain controllers, it cannot perform authentication and authorization, and network access authentication will fail.
