Just pointing out that the combination of VNC and ZoneAlarm has caused
problems in the past.  The next step to persue would be to take a network
trace (Network Monitor, Ethereal, etc.) of this traffic to see what it is.
 I don't recall ever seeing VNC need internet access with the exception of
DNS.
