"The remote peer does not support the required VPN Client protocol"
Explanation: Another odd error.. Usually you should check the IP or hostname in the connection entry to make
sure it is the correct one.. or maybe if you haven't used your VPN client in a long time.. check with your systems
admins to check to see if they have renamed (or given a new IP) to the Cisco VPN server, or maybe even replaced the
Cisco VPN server with a different vendor's VPN server but kept the old IP.
