TightVNC server not listening for connections
Solution 1:
I found out what the reason was. It:s because TightVNC server was already running as a service. Its icon doesn't show until a connection is made. If you try to run the TightVNC server program while the service is already running then thats what happens.
Solution 2:
I had the same probleme (thightVNC service not listening), so I put 5901 on "deskA computer and 5902 on the other one( DeskB). Then from my desk if I want to be connected, I search for deskA:1 and for the other one deskb:2
Solution 3:
I found the reason my server wasnt listening was because realvnc was installed but didnt have a taskbar icon so tightvnc got installed too.
removed realvnc and left tightvnc running
Solution 4:
It definitely means something else in using the port. Change it to 5801, 5901, etc. and the server will start listening.
