Disable UAC and warning dialog?

I have disabled UAC on a Vista machine so that I can connect to it from
a remote location and change its configuration. However, every time the
Vista machine is restarted a window opens above the tray telling the
user that UAC is off and that they should "click here" to turn it on.
From ignorance or carelessness the user frequently clicks the window
and re-enables UAC. How can I prevent this message from appearing?

I want UAC off on this machine and I want it to stay off! Thanks.
