    You must have forgotten some files or something, it's something that
    works. I've put online a reader-enabled summary of my notes about
    VNC/Java/etc. at:

      

    The way to do that is in point #1...

    VB? You could do it simply using the SLEEP.EXE utility from NTRK
      :Disconnect
      <your stuff>
      SLEEP 600
      GOTO Disconnect
    or, similarly, using SOON.EXE at the end of the batch so that it always
    schedules itself for being executed again N seconds in the future.

    The annoying thing here is that vnc is restarted independantly of the
    user's session: one could connect in the applet and then be possibly
    forcefully disconnected just a few seconds later -- it is not a
    "disconnection after N minutes of use".

    OTOH, the good point is that it's not possible to cheat, if those
    repeated disconnections are important for you. Using a browser-driven
    META-refresh scheme, it's always possible for someone really wanting it
    to avoid being disconnected...

    That's nothing curious: after restarting WinVNC service on NT you have
    to rerun the Service Helper, i.e.:
      winvnc.exe -servicehelper
    so as to make trayicon come back. More importantly, while you don't do
    that, WinVNC will use your "Default settings" (especially the password)
    instead of "User settings".
