One of my clients just changed over to a Cisco VPN (5.0.05.290), but after it was installed,
my dear old XP box would hard crash at the Comodo add network dialog on submit. Nasty...
I found a solution which is to install the VPN client without the firewall which contains ZoneAlarm stuff?
Basically extract the installer and run it with
msiexec.exe /i vpnclient_setup.msi DONTINSTALLFIREWALL=1
