Event ID 20213 — RRAS NAP and Network Access Quarantine Control

Updated: December 16, 2008

Applies To: Windows Server 2008 R2

yellow

Network Access Protection (NAP) provides a platform to help ensure that client computers on a private network meet administrator-defined requirements for system health. NAP enforcement occurs at the moment client computers attempt to access the network through network access servers, such as a virtual private network (VPN) server running Routing and Remote Access, or when client computers attempt to communicate with other network resources.

Network Access Quarantine Control is similar in function to NAP VPN enforcement, but it provides added protection for remote access connections only. NAP provides added protection for Internet Protocol security (IPsec)-based communications, 802.1X authenticated connections, VPN connections, Dynamic Host Configuration Protocol (DHCP) configuration, and Terminal Services Gateway (TS Gateway) connections.

Diagnose

This error might be caused by one of the following conditions:

  • NAP scenarios are not working. See section titled "Restart or enable the NAP Agent service, enable remote access quarantine enforcement client, or retry remote access connection."
  • Correlation ID mismatch occurred. This might be due to the response to an earlier request.
  • The connection has been disconnected because the Session Timeout received from the RADIUS server has expired. See the section titled "Check the NPS configuration."
