Server 2008 RAS Demand Dial VPN

[fenton]

Do you receive Event ID 20111?. This is the fix from Microsoft.NT 4, not sure it will apply to 2008.

Demand-Dial Interface Is Unreachable:

When a demand-dial interface reconnects after the WAN link has been disconnected, an error might appear in the Event Log. Also, in Routing and RAS Admin, the Connection State for the interface is temporarily marked unreachable.

The event logged in Event Viewer is the result of a timing condition and is incorrectly marked as an error. It should be marked as information because the router recovers and successfully reconnects the interface in these cases.

The event logged in Event Viewer is the following:

Event ID: 20111
Source: Router
Event Description: A Demand Dial connection to the remote interface <interface name> on port <port name> was successfully initiated but failed to complete successfully because of the following error: The interface is already connected.

Connect to Third-Party Routers:

You can enable a Windows NT router to request an IP address when you connect to third-party routers through demand-dial interfaces.

To enable a Windows NT router to request an IP address:

1. In Network in Control Panel, on the Services tab, select Routing and Remote Access.

2. Click Properties, and then click Network.

3. In the Network Configuration dialog box, click the TCP/IP Configure button.

4. Select the Allow remote clients to request a predetermined IP address check box.

Removing an Interface when the Router is stopped In Routing and RAS Admin, if you remove a demand-dial interface when the router is stopped, the interface is removed from the Registry, but is left behind in the router phonebook file. If you want to add the interface again and you continue to receive the error "interface already exists," you must delete the entry from the router phonebook file.

To delete an entry from the router phonebook:
