[AccessD] OT: VNC client doesn't display

John - I struggled getting VNC working for some clients (and I still haven't succeeeded with some) but for most I just had to permit VNC through their  firewall, which you've done and then on my PC completely shut down ZoneAlarm to let it through. For now shut down ALL firewalls (as opposed to just changing the settings) to see if that is the problem.

If that isn't any help then I would go to http://www.realvnc.com/lists.html and subscribe to their VNC forum so that you can then post a question - I have found them quote helpful.

  Subject: [AccessD] OT: VNC client doesn't display


  I am trying to setup VNC to run on my sister-in-law's computer so that I can
  do tech support.  Windows XP Home on her machine, Windows XP Pro on my
  laptop.

  I set up no-ip.com so that there is a dynamic tracking of her IP address.
  I set up the server on her machine and it seems to be running.
  I set up the firewall to do port forwarding to her machine
  I run the client on my laptop and attempt to connect to her machine.  

  I have a couple of issues, but the immediate issue is that the client runs,
  doesn't give any error message, but also doesn't pop up the login screen,
  nor display anything at all.  If I look in Task manager, VNC Client is
  running in the Processes tab but NOT in the Applications tab.  If I try to
  start it again, connecting to her machine, ANOTHER copy of the VNC viewer
  opens, does not display, but appears in Task Manager.  If I run it again,
  and connect to a client where I VNC in all the time, ANOTHER copy opens,
  displays the login screen, and allows me access to the desktop of my client.
  Thus it appears that it is something to do with connecting to the server on
  her machine.  

  I run Sygate personal on both my Laptop and on her machine.  It has been in
  place and functioning on both machines for months.  IF I try to log in to
  her machine with the firewall running, I get a "can't find the host" kind of
  message from VNC, so I know that the VNC requests are getting out to the
  web, through the No-IP translation, back to her router, THROUGH her router,
  and are blocked by Sygate if it is running on her machine.  That in itself
  is the other problem since I have VNC.EXE listed in Sygate as "allowed", but
  I need to tackle one problem at a time.  I disable the Sygate router on her
  end and then the VNC client I am trying to connect just silently connects
  but will not display.

  Does anyone have a clue what is happening here?  I have tried to find these
  symptoms on Google but come up empty.
