RADIUS Client Communication
Applies To: Windows Server 2008 R2
Network Policy Server (NPS) exchanges RADIUS messages with RADIUS clients. RADIUS messages exchanged between NPS and RADIUS clients must comply with the RADIUS protocol specification or NPS might not be able to process connection requests.
