You may be not able to use a VPN connection again on a computer that is running Windows Server 2008 or Windows Vista if you log off the computer without disconnecting the VPN connection
Consider the following scenario. On a computer that is running Windows Server 2008 or Windows Vista, you use Connection Manager to create a VPN connection to a Routing and Remote Access Service server. The VPN connection is created successfully. Then, you log off the computer without disconnecting the VPN connection. In this scenario, when you log on to the system again and open the Network Connections window of Connection Manager, you may find that the status for the VPN connection shows “Disconnecting….” Therefore, you may be not able to use this VPN connection again without restarting the computer.
- If you check the VPN connection in the Routing and Remote Access console on the server side, you notice that the connection is disconnected.
- You can still manually create a VPN connection to the Routing and Remote Access server without using Connection Manager.
- To use the VPN connection in Connection Manager again, you must restart the computer.
