NPS Authentication Status

Updated: February 21, 2008

Applies To: Windows Server 2008

When Network Policy Server (NPS) is configured as a RADIUS server, it performs authentication, authorization, and accounting for connection requests received from configured RADIUS clients. If authentication and authorization are successful, users and computers are granted access to the network resources for which they have permissions.
