red

A demand-dial interface is a logical interface that represents a point-to-point connection. The point-to-point connection is based on either a physical connection, such as two routers connected over an analog phone line that uses modems, or a logical connection, such as two routers connected over a virtual private network (VPN) connection that uses the Internet. Demand-dial connections are either on-demand (the point-to-point connection is only established when needed) or persistent (the point-to-point connection is established and then remains in a connected state). Demand-dial interfaces typically require an authentication process to become connected. The equipment required by a demand-dial interface is a port on a device.

Resolve

Review the remote access service error code

There is not enough information available in the Routing and Remote Access service event message to provide a recommendation for resolution of the problem. If you continue to get this error, contact Microsoft Product Support Services. For more information, see http://go.microsoft.com/fwlink/?LinkId=52267.

Verify

If the calling router uses a dial-up connection to the local ISP, the local ISP assigns the router a temporary IP address. You can confirm that this IP address exists by typing ipconfig at a command prompt.

To perform the following procedure, you must be a member of the Administrators group, or you must have been delegated the appropriate authority.

To check the status of the demand-dial interface:

  1. Open Routing and Remote Access. Click Start, click Run, type rrasmgmt.msc, and then press ENTER.
  2. In the console tree, click Network Interfaces.
  3. In the details pane, in the Connection State column, verify that the demand-dial interface that matches the user name for the credentials of the calling router is connected.
