Lee:
Wow, that is a weird one. Please try this: open a command
window on your VNC Viewer PC (Start -> Run -> "cmd"), and type
"netstat -an". Check to see if anything is running with a connection
to your target VNC Server's TCP port 5900.
To disable blacklisting on your VNC Server, do this:
1. Start -> Run -> "regedit"
2. Add a new registry string value here:
HKEY_CURRENT_USER\Software\RealVNC\WinVNC4 (for user-mode)
HKEY_LOCAL_MACHINE\Software\RealVNC\WinVNC4 (for service-mode)
3. Name the new registry string "BlacklistTimeout".
4. Set the value to "0".
From what you describe...it sounds like something on
your VNC Viewer PC is periodically connecting to your VNC Server
PC's TCP 5900, causing the blacklist time period to extend
indefinitely. The above "netstat" command should help you to
detect if that's the case; you'll need to run a "process to
port" mapper to actually discover the software application that's
doing it though:

Hope that helps!

Hi Scott,
When I try to connect from the viewer computer it gives the error
"connection disconnected unexpectedly", so it is connecting,but not keeping
the connection. When I check the Windows XP event viewer under application
on my host computer it reads Connections: the IP address of the server
computer and the term blacklisted. I can connect to the host computer from
other computers(my wifes work computer). What else can be happening to block
this one computer. As far as I can tell I have opened up the correct ports
on Norton and it should be a go. What does it sound like to you?
