Event ID 20211 — 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.

Event Details

Product: Windows Operating System

Version: 6.1
Symbolic Name: ROUTERLOG_RASQEC_PPPREINIT_FAIL
Message: The Network Access Protection (NAP) enforcement client could not start PPP renegotiation on the following remote access connection: %d. Some network services or resources might not be available.

Resolve

Fix PPP renegotiation

ROUTERLOG_RASQEC_PPPREINIT_FAIL

A change in system health resulted in a new SoH. The PPP renegotiation that was started to send this SoH to the server failed. Because there has been no change in the parameters negotiated during PPP, the most common cause of this problem is network connectivity between the client computer and server. Network problems can result in the delay or loss of PPP requests and responses during negotiation. Check the status of network connectivity in the Network Connections folder.

For network problems, contact the ISP or network administrator to determine the status of the network.
