Network Policy Server (NPS)

Applies To: Windows Server 2008

Network Policy Server (NPS) provides authentication, authorization, and accounting services for network access servers, such as IEEE 802.1X authenticating switches and wireless access points, virtual private network (VPN) servers, dial-up servers, and computers running Windows Server 2008 with Terminal Services Gateway (TS Gateway).


The following is a list of all aspects that are part of this managed entity:

Name Description

NPS Accounting Request Message Processing

Network Policy Server (NPS) receives accounting request messages from configured RADIUS clients. Depending on the accounting configuration of the server running NPS, the accounting request will be logged in either a log file or a SQL Server database.

NPS and Domain Controller Communication

If NPS cannot contact domain controllers, it cannot perform authentication and authorization, and network access authentication will fail.

If authentication and authorization are successful, users and computers are granted access to the network resources for which they have permissions.

NPS License Compliance

The Network Policy Server (NPS) configuration must comply with the Windows operating system license restrictions for the component.
