I didn't see anywhere in the thread where anyone said you can't enumerate
the settings with scripts. MS hasn't exposed any functionality like that,
you could read the text files directly and try to work it out yourself
though. The only thing you can get from AD is that the GPOs are linked in
certain areas and what files they are linked to. The GPMC script extensions
don't do much more, they just wrap up the AD properties into nice titles.
