VNC Beta V4.0b4 with ZoneAlarm Pro V4.5.530.000 on Win2K Pro Desktop

[Andy]

Hi, I'm new to this list but I've been a happy user of VNC for a couple of
years, never had a problem. I recently was looking for a more reliable (less
timeouts, etc...) version of VNC and found the RealVNC site and a beta
download of their latest program, V4.0b4.

I installed the beta version on top of an older VNC V3.3.3 (which I
eventually removed) and immediately had problems getting it to work. I
narrowed the problem to Zone Alarm Pro, since when I shutdown ZAP, VNC works
and when I start it back up VNC stops working.
I've confirmed the PC's on my home network are properly configured in ZAP
and I even tried individually configuring them in ZAP, but this does not fix
the problem. The only thing I can get from ZAP is a message when I first
start VNC, saying that ZAP blocked the attempt, but I does not say why and
it also does not recognize the protocol. I posted a similar question to the
ZoneAlarm site and am awaiting a reply.

Is anyone experiencing a similar issue? I'm open to any and all suggestions.

Thanks,

Andy
