    So technically there's the possibility that privileges may change during
    the time between logon and whenever XP finishes processing the Group
    Policy/Security Policy/Wallpaper Policy? Can I ctrl-alt-del and kill
    whatever process is still parsing the policies?

    Is loopback processing on by default?

    I wasn't implying that RSoP had anything to do with processing although
    looking again I can see why you'd come to that conclusion. I only meant
    that whatever the RSoP _happens to be_ gets applied, not that you can
    change it _using_ RSoP.

    I'm never really awake until 11am no matter when I get up.
