Network Policy Server
From Wikipedia, the free encyclopedia
Network Policy and Access Services (NPAS)[1] is a component of Windows Server 2008. It replaces the Internet Authentication Service (IAS) from Windows Server 2003. The NPAS server role includes Network Policy Server (NPS), Health Registration Authority (HRA), and Host Credential Authorization Protocol (HCAP). In Windows Server 2003, IAS is the Microsoft implementation of a Remote Authentication Dial-In User Service (RADIUS) server. In Windows Server operating systems later than Windows Server 2003, IAS is renamed to NPS.
NPS is a role service in Windows Server 2008 which can function as:
- RADIUS server
- RADIUS proxy
- Network Access Protection policy server
