There's a couple of possibilities:

If you launched the server code via "vncserver" or something like that,
then make sure your vnc client is trying to access "hostname:1" (since
the X vnc server will be on display 1, not the default of 0.

If you included the "vnc" module in your xorg.conf, then you will be
sharing the primary display between the normal X display and the VNC
client.

If you set up the VNC server to tunnel through ssh, you need to tell the
VNC client to tunnel through ssh as well.  On the Linux "vncviewer"
command, this is indicated by using the "-via ssh-gateway-name" option
on the command line.  I don't know what the equivalent is on RealVNC on
Windows.

As to the server-side log entries, don't worry about them.  They're
simply telling you that you don't certain fonts installed.  It's not
fatal.
