RADIUS clients are network access servers or devices. If you specify a RADIUS client in NPS, then the corresponding RADIUS server configuration is required on the RADIUS client device. For example, remote HRA servers are configured as RADIUS clients on NPS.
If the NAP enforcement server is located on the same server as the NAP health policy server, then you do not need to configure RADIUS clients unless you are using the VPN enforcement method. When you install NPS on a server running the Routing and Remote Access service (RRAS), the local server is automatically configured as a RADIUS client in NPS. This is because RRAS automatically provides RADIUS client software.
