CISCO VPN Client Error message "Reason 442: Failed to Enable Virtual Adapter"

Problem Description: When users will try to establish VPN connection that cannot establish a connection. A pop-up message will apper with error message "Reason 442: Failed to Enable Virtual Adapter". If you are looking at the status bar of the VPN client you will see this pop-up appearing after VPN client was showing "Securing communication channel..."





Cause: Problem with the network adapter configuration that VPN client uses, some time it does not get disabled because someone might have closed laptop and it didn't get terminated properly.





Fix: There are usually two things that work for me


Fix1: Disable "Local Area Connection (x)" that is created and used by CISCO VPN Client. Following are steps on how to do this:





Windows XP:


1. Navigate to network connections by selecting Start >Settings > Control Panel > Network Connections


2. Set the view to show you details (Select 'View' menu on the top and select 'Details')


3. Under Device name column one should be able to see which Local Area Connection is used by CISCO Client. Here is a screenshot:

4. Right click on Local Area Connection that is used by VPN client and disable it (if its already enabled).

5. In case Local Area Connection used by VPN client is disabled then select repair.

FIX 2: This has to do with Windows VISTA specificly.
