RADIUS clients are network access servers or devices. If you specify a RADIUS client in Network Policy Server (NPS), then the corresponding RADIUS server configuration is required on the RADIUS client device. For example, remote Health Registration Authority (HRA) servers are configured as RADIUS clients on NPS.

If the Network Access Protection (NAP) enforcement server is located on the same server as the NAP health policy server, then you do not need to configure RADIUS clients.
