Please check the result of the following commands:
Enter 10000 (10 seconds) then test again the remote control. This delay is the time between the request to start the "VNC Server / WinVNC" service on the remote host and the first connection attempt on this computer : " Tools" menu, " TightVNC Options", " General" tab. You can also try to increase the delay of synchonization with the WinVNC server (2000 milliseconds by default).For example enter the port 5901, then try again by lauching the remote control. Please try to enter another port number (right click on the remote host, Remote control, Configurer, Connection tab).
