If you've tried everything else, download free trial of Ethereal and sniff the port. It will tell you if anything is making it in. It sounds to me like "something" is blocking what you've got.

On a more local note--when you run VNC in service mode you should get the VNC icon showing up on your system tray. Try flying over it and see if you get a display like "VNC Server (Service): 192.168.1.105" (that's my local address, obviously to have it NAT'ed through the router I have to enable port forwarding to my local box).

I've found it's not unusual for someone to flyover their systray item and it happily reports that the VNC server isn't really listening. Also, the VNC server could possibly be bound to the wrong network connection if you have multiple network cards in your box.

Cheers,

Andy

New to VNC and new to networking in general but like most everything, I jump
right in.  I have VNC Server set up in service mode on my home PC (XP).
Every attempt to connect to my server PC from an outside internet connection
has been blocked.  I can connect to other PCs with the viewer and I can
remotely access my PC with my laptop when it is connected to the LAN.  Port
5900 is wide open and can be sniffed by gotomyvnc.com.  I have read many
other posts regarding connectivity issues and tried several of the solutions
with no success.  I am concerned that there is a software program that is
blocking the connection.  I have Windows Firewall diabled and even tried
completely disabling my ZoneAlarm Firewall with no luck.


Could this be the result of a program blocking the connection or VNC Server
rejecting the connection?
