That really sounds like the VNC server is not listening. Right-click on the
VNC icon in the system tray and select "options." Go to the "Connections"
tab and make sure that the box marked "Accept connections on port xxxx" is
checked and that it's got 5900 in there (you can change that later if you
choose, but for testing purposes...) Again, I'd re-enable the firewall and
put the winvnc4.exe as "allowed" in the firewall. Also, one last thing...
check to see what you have in the "access control" window at the bottom...
make sure it's got "+0.0.0.0/0.0.0.0" which will allow open access if you
know the password. Or, if you're coming from a firewall and you *know* for a
fact what the external IP is, you can try putting that in there and limit
access to only the external IP, but I wouldn't recommend it. Check the
archives of the RealVNC list for a message from James Weatherall dated

Adam Trenthor for more information on this.
I may be way off base on these suggestions but at least they're a starting

Thanks for coming back to me.
I've been using a DynDNS alias for home, but that doesn't work either. As I
can see my work PC from home, I've tried putting in the current IP, with no
success. Today I'm sitting here in my office with both machines on my desk,
with fixed IPs on the same network and STILL no success!
I've just run the scan from gotomyvnc.com on home laptop and it came up with
a complete list of 'not responding'. So that means....?
I have one VNC icon in the laptop system tray, which confirms it is
(Service) with the current IP.
As I said, if I turn off the Windows Firewall on the home laptop the problem
changes from a timeout to a 'closed unexpectedly' message.
So, does the 'not responding' give you a clue? I'm lost.....

Do you have a router on your internet connection at home? Also, what address
are you using to connect to home? Most internet providers assign IP
addresses randomly, so the IP address you have today may not be the same one
you get tomorrow or next week. I'd suggest your first step would be to
verify that your port-forwarding in your router (if any) is working
correctly by going to http://www.portforward.com and checking the
instructions for your router there (if there are instructions for any router
you have.) Second, from home, visit http://www.gotomyvnc.com and have the
system there scan your network to see if it can find any listening VNC
servers. Third, double-check that you have VNC installed as a service, not
as a user-run app. Also, double-check on your XP firewalls that you have
enabled winvnc.exe to pass through the firewall. That may not solve the
problem, but it would definitely make things easier.
James or someone else may have some other suggestions, but that's what I'd

I've used VNC free edition happily for a couple of years to link my office
and home pcs, so I can see both at all times.
Since changing machines at both ends, I've had endless problems. I
downloaded the latest editions and, after much trying, have managed to
establish the link so I can see my office PC from new laptop. Can I get it
to work the other way? Can I ****!
Both machines on Windows XP Home, latest updates.
When I try to connect from office, I enter IP address and wait.and
wait..until I get a timeout. If I switch off Windows Firewall at home, I
get the Connection closed unexpectedly message.
I've tried deleting and reinstalling VNC, but can't get it right.
Obviously doing something very stupid, can anyone help?
