Hi,

without any error message.
But the VNC tray icon doesn't appear.
 
When I issue command > winvnc4 -connect xxx.xxx.xxx.xxx

main:   Unable to locate existing VNC Server.
 
But it is ok when I issue the command to port 5500 as : telnet
xxx.xxx.xxx.xxx 5500
 
Is anyone known the problem and can help me out ?
 
Thanks a lots.
 
Cheers
