Make the disconnect network feature work properly if users have multiple NICs / Interfaces or for when it is run by a Windows 10 user who is not admin.

1. If you have a interface which is local LAN traffic, then do not take that out of service.
2. When the network is taken down, you should still allow access to the VPN servers so the app can reconnect, as often you have to restart the app to reconnect.
3. All functions should work the same for standard users of Windows.
