Event ID 20139 — RAS Connection Termination

  • Article

Applies To: Windows Server 2008

Remote access involves establishing 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.
