Event ID 20127 — RRAS Routing Interfaces

  • Article

Applies To: Windows Server 2008 R2

The server running Routing and Remote Access uses a routing interface to forward unicast IP and multicast IP packets. There are two types of routing interfaces: LAN interfaces and demand-dial interfaces. A LAN interface is a physical interface that typically represents a local area connection that uses local area networking technology such as Ethernet or token ring. 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.

Diagnose

This error might be caused by one of the following conditions:

  • The network interface is disabled or not connected to a network.
  • The Routing and Remote Access service is stopped.

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

Network interface is disabled or not connected to a network

  1. Confirm that the network interface card is physically connected to a network.
  2. Open Network Connections, and check the status of the network device.
  3. If the status is Disabled or Unplugged, see the section titled "Enable network devices or services" or "Check the network connection."

Routing and Remote Access service is stopped

  1. Open Routing and Remote Access. Click Start, click Run, type rrasmgmt.msc, and then press ENTER.
  2. In the console tree, click Server Status.
  3. Determine if the status of the Remote Access service is started.
  4. If the Remote Access service is stopped, see the section titled "Enable network devices or services."

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 the resolution of the problem. If you continue to get this error, contact Microsoft Product Support Services. For more information, see https://go.microsoft.com/fwlink/?LinkId=52267.

For more information about remote access service error codes, see article 163111 in the Microsoft Knowledge Base (https://go.microsoft.com/fwlink/?LinkID=91455).

Check the availability and response of the modem or other connection device

Possible resolutions include:

  • If the modem was disconnected or turned off, reconnect or turn on your modem, and then either restart the operating system or use Device Manager to scan for new hardware.
  • If the communications port is already in use by another connection, end the connection or change the connection to use a different port.

Configure dial-out time restriction

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

To configure dial-out hours:

  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, right-click the demand-dial interface you want to configure, and then click Dial-out Hours.
  4. In the Dial-out Hours dialog box, select the appropriate day and time boxes to either permit or deny dial-out access, click either Permitted or Denied, and then click OK.

Check the network interface card

Reconnect or reinstall the network interface card used for remote connections.

Check the network connection

Reconnect the network interface card used for remote connections.

Upgrade the operating system

Upgrade the operating system on the remote access server to an operating system that supports demand-dial interfaces, such as Windows Server 2003 or Windows Server 2008.

Verify

To verify that the remote access server can accept connections, establish a remote access connection from a client computer.

To create a VPN connection:

  1. Click Start, and then click Control Panel.
  2. Click Network and Internet, click Network and Sharing Center, and then click Set up a connection or network.
  3. Click Connect to a workplace, and then click Next.
  4. Complete the steps in the Connect to a Workplace wizard.

To connect to a remote access server:

  1. In Network and Sharing Center, click Manage network connections.
  2. Double-click the VPN connection, and then click Connect.
  3. Verify that the connection was established successfully.
