This is the Microsoft Network Policy Server (NPS) Technical Reference for Windows Server 2012 R2, Windows Server 2012, Windows Server 2008 R2, and Windows Server 2008. In these products, NPS is a networking server role that allows you to create and enforce organization-wide network access policies for client health, connection request authentication, and connection request authorization. You can configure NPS to perform as a Remote Authentication Dial-In User Service (RADIUS) server, RADIUS proxy, Network Access Protection (NAP) policy server, or as any combination of these, for incoming connection requests from virtual private network (VPN), 802.1X wireless access point or authenticating switch, or dial-in network access servers.

This technical reference includes content that might not be available elsewhere on the Web in the future, including information about registry keys, SQL Server stored procedures, authentication methods and processes, authorization methods and processes, and NPS architecture.
