Network Policy and Access Services Role
Updated: January 21, 2008
Applies To: Windows Server 2008
Network Policy and Access Services (NPAS) in the Windows Server® 2008 operating system provides technologies that allow you to deploy virtual private networking (VPN), dial-up networking, and 802.11-protected wireless access. With NPAS, you can define and enforce policies for network access authentication, authorization, and client health using Network Policy Server (NPS), Routing and Remote Access Service, Health Registration Authority (HRA), and Host Credential Authorization Protocol (HCAP).
You can deploy NPS as a Remote Authentication Dial-in User Service (RADIUS) server and proxy and as a Network Access Protection (NAP) policy server. NAP helps you ensure that computers connecting to the network comply with the network and client health policies of your organization.
