Here are a couple of additional things you could try and which may give you a clue where things are going wrong:
1) At a command prompt "net start" will return a list of running services. You should see "VNC Server" if the VNC Server is really started. If it's not, "net start "VNC Server"" will try to start it. If it will not start, you may get a clue why in the error message. If it is started, "net stop" will try to stop it. If it will not stop you may get a clue why in the error message. 2) At a command prompt "netstat -an" will return a list of connections and listening ports in numerical form. Among the results, you will see TCP 0.0.0.0:5800 0.0.0.0:0 LISTENING TCP 0.0.0.0:5900 0.0.0.0:0 LISTENING if the VNC Server is listening on the standard ports. If the VNC Server were listening on a non-standard port you would see something else, e.g., if the VNC Server were listening on display 42, you would see TCP 0.0.0.0:5842 0.0.0.0:0 LISTENING TCP 0.0.0.0:5942 0.0.0.0:0 LISTENING If, after stopping the VNC Service, you still see a line like TCP 0.0.0.0:5800 0.0.0.0:0 LISTENING or TCP 0.0.0.0:5900 0.0.0.0:0 LISTENING there is something else using the ports that VNC Server wants before VNC Server is getting a chance to grab them. 3) At a command prompt, with the current working directory of your VNC directory "winvnc -servicehelper". This should add a VNC icon to the tray (next to the clock) if one is not already there. When you double-click on it you will get its configuration options which you can compare with a working server. Good luck. ----- Original Message ----- From: "Dilash Krishnapillai" <[EMAIL PROTECTED]> To: <[EMAIL PROTECTED]> Sent: Wednesday, May 29, 2002 11:38 AM Subject: RE: Cannot connect to the VNC server > Thanks for the information.
