This mean that vnc is already running. LOL
It could be as service ...

Check taskmgr ( all users) for winvnc.exe

Check taskmgr ( all users) for winvnc.exe

The service of winvnc.exe run as SYSTEM in session 0 and the desktop part run in the desktop session.
If you don't check all users, you only see yourself
If you kill the desktop part with taskmgr, the service auto restart it in a few seconds.

It can also be another vnc flavor.

you can check with netstat -abn what software is listening on port 5900/5901...
cmd ( start with runas admin)
