Updated: February 29, 2012

Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012

When you add a new network access server (VPN server, wireless access point, authenticating switch, or dial-up server) to your network, you must add the server as a RADIUS client in NPS, and then configure the RADIUS client to communicate with the NPS server.

ImportantImportant
Client computers, such as wireless portable computers and other computers running client operating systems, are not RADIUS clients. RADIUS clients are network access servers—such as wireless access points, 802.1X-capable switches, virtual private network (VPN) servers, and dial-up servers—because they use the RADIUS protocol to communicate with RADIUS servers such as Network Policy Server (NPS) servers.

This step is also necessary when your NPS server is a member of a remote RADIUS server group that is configured on an NPS proxy. In this circumstance, in addition to performing the steps in this task on the NPS proxy, you must do the following:

  • On the NPS proxy, configure a remote RADIUS server group that contains the NPS server.

  • On the remote NPS server, configure the NPS proxy as a RADIUS client.

Task requirements

The following are required to perform the procedures for this task:

  • You must have at least one network access server (VPN server, wireless access point, authenticating switch, or dial-up server) or NPS proxy physically installed on your network.

To complete this task, perform the following procedures:
