Event ID 20220 — RAS Connection Establishment

  • Article

Applies To: Windows Server 2008

Remote access involves the establishment of a dial-up or broadband connection with a remote access server. A dial-up client that connects to a server running Routing and Remote Access can be any PPP client. The client must have installed a modem, an analog telephone line or other wide area network (WAN) connection, and remote access software. Virtual private networking (VPN) clients that connect to Routing and Remote Access must be able to send TCP/IP packets to the remote access server over the Internet. Therefore, either a network adapter or modem with an analog telephone line or other WAN connection to the Internet is required.

Fix problems with RAS connection establishment

The establishment of a RAS connection for Internet or VPN connectivity takes place in stages. The successful completion of a stage is indicated by the generation of an informational (success) event. The failure of RAS connection setup is diagnosed based on the last informational event generated and the error code that accompanies ROUTERLOG_RASCONNECTION_FAILED (Event 20227).

The problems that might cause the failure are divided into the following categories:

  • Hardware issues
  • Network connectivity
  • VPN tunnel settings
  • IPsec security associations
  • PPP user authentication and negotiation issues
