    Default GPO loopback mode

    I think I figured this out by typing it all here and thinking about it more... This is how this works (NO ONE has a diagram like this online... this would make so much more sense)

    How GPOs are applied

    Normally

    OU A (which hosts users) has group policy B applied

    GP B has
    computer settings
    user settings

    User settings are only applied

    OU B (which hosts computers) has group policy B applied

    GP B has
    computer settings
    user settings

    Computer settings are only applied

    Loopback processing mode applied REPLACE

    OU A (which hosts users) has group policy B applied

    GP B has
    computer settings
    user settings

    NO settings are only applied

    OU B (which hosts computers) has group policy B applied

    GP B has
    computer settings
    user settings


    All settings are applied

    Loopback processing mode applied MERGE

    OU A (which hosts users) has group policy B applied

    GP B has
    computer settings
    user settings

    User settings are only applied FIRST

    OU B (which hosts computers) has group policy B applied

    GP B has
    computer settings
    user settings


    All settings are applied

    basically user settings are ignored


    Loopback processing mode applied MERGE

    The user policy settings applied are the combination of those included in both the machine and user GPOs. Where conflicts exist, the machine GPOs "win".

    agree with Mishra

    Thats kind of a long way to describe it, and honestly I didn't follow.

    Normal Mode:
    1. Computer Settings
    2. User Settings

    Loopback mode:
    1. Computer Settings
    2. User Settings
    3. Computer Settings (From the GPO linked to the user)

    In replace mode, the step 2 settings are forgotten. In merge mode, both settings are added together with the computer settings having a higher priority (because they were applied last)

    That's how it passes through my brain.
