To go back to the original problem, and my post:-
What is the Cisco Systems VPN Adapter?
The VPN Adapter is a "software-only" driver that provides an interface to solve protocol incompatibility problems. With this installed, more applications are able to run while connected with the VPN client. Removing this adapter from your
Network Connections Control Panel may cause the VPN client to stop working properly.
See the
Cisco Release Notes for more information on the VPN Adapter.
