You say Windows-based VNC clients don't work. Do Linux-based VNC clients
work? It wouldn't be a solution, but it might be useful to help understand
the problem. Also, have you tried any other windows-based VNC clients?
Have you tried manually starting the vino vnc server from the command line?
There's some interesting stuff here on how to control vino a little better:

You could also (as a workaround), try installing vnc4server and starting it
from the command line. That might help get you going.
