  • Lets say we have :

    1.  OU for Computers called Computer which contain one computer : Win8 and one user : Jack Heron

    2. OU for Users called Users and contain some users …like Siyamand Rashid

    We create a GPO called GPO1 and link it to Computer’s OU and configure both Computer and User configurations.

    And create another GPO called GPO2 and link it to User’s OU and configure both Computer and users configurations.

     

    Scenario 1  : ( Without Loobpack process involved ):

    So when WIN8 will start a computer settings from GPO1 will applied  ! , when the Users Jack Heron is login a User settings from GPO1 will applied also as he is inside the same OU.

    But when a user Siyamand Rashid is login to Win8 a user settings from GPO2 will be applied ! and not from GPO1

     

    Scenario 2 : (Loopback replace mode enabled )

    If loopback enabled with replace mode this will happens

    When computer starts up the computer settings from GPO1 will applied , and when user Jack Heron login a user settings from GPO1 will applied as he is inside same OU.

    When user Siyamand Rashid Loges in to WIN8 , user settings from GPO1 will be applied as it will replace the GPO2 users settings.

     

    Scenario 3: (Loopback with merge mode enabled)

    When computer starts up the computer settings from GPO1 will applied , and when user Jack Heron login a user settings from GPO1 will applied as he is inside same OU.

    When User Siyamand Rashid log in to WIN8 , user settings from GPO2 and GPO1

  • If the policy settings conflict, the user policies in the computer's Group Policy objects take precedence over the user's normal policies.

    which mean the background which you configured in GPO1 will be applied !

  • thank you for your quick reply,

    you mentioned in Scenario 3 :

    When User Siyamand Rashid log in to WIN8 , user settings from GPO2 and GPO1

    so for example if in GPO1 I set a background , and also the GPO2 a set another background which background will be applied ?
