The other day I had a computer that needed to automatically connect a VPN tunner on startup. Apparenty the Cisco VPN Client 4.6 and later has a Command-Line Interface so this can be done using this line in a batch-file.

         start /wait vpnclient.exe connect VPN-Profile user username pwd password

It has a couple of other CLI-Switches:
