Event ID 20111 — RRAS Demand-Dial Connections

Updated: December 16, 2008

Applies To: Windows Server 2008 R2

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.

Event Details

Product: Windows Operating System
ID: 20111
Source: RemoteAccess
Version: 6.1
Message: A demand-dial connection to the remote interface: %1 on port: %2 was successfully initiated but failed to complete successfully because of the following error: %3


Reinitialize the demand-dial connection

Check that there is communication between the calling and answering demand-dial routers.

To initiate the on-demand connection on the calling router:

  1. On the calling router, in the Routing and Remote Access snap-in, click Network Interfaces.
  2. Right-click the demand-dial interface for which you want to initiate a connection, click Connect, and then confirm that the connection was established.


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.
