Re: VPN Client Connection Problem - The VPN Client could not fin

Before adding or removing any network adapters from the Network Control Panel, uninstall the VPN Client, and reboot the computer. After the adapters are configured appropriately, reinstall the client. If this procedure is not followed you may experience system instability upon rebooting after adapters have been added or removed. You can recover by starting your Windows system in Safe Mode, uninstalling the client, rebooting, and then reinstalling the client.
