Event ID 20214 — VPN NAP Enforcement Client Configuration

  • Article

Applies To: Windows Server 2008 R2

A Network Access Protection (NAP) enforcement client is responsible for requesting access to a network, communicating a client computer's health status to the NAP server that is authorizing the network access, and communicating the connection status of the client computer to other components of the NAP client architecture. A NAP-capable client is a computer that has the NAP components installed and can verify its health state by sending a statement of health (SoH) to NPS.

The remote access enforcement client enforces health policies when a client computer attempts to gain access to the network through a virtual private network (VPN) connection.
