Group Policy Object 2

If more than one GPO is linked to an active directory container, which policy will take precedence?

If more than one group policy object is linked to an active directory container object, GPOs are processed from the BOTTOM to TOP as they are listed on the GPO tab in the properties dialog box. Again where there is a conflicting in setting the last setting applied becomes the effective settings.

Organization Unit limitation?

Microsoft recommends as OU structure that is not more than 10 top levels deep increasing the number of nested relationships adds to the complexity of permission and group policy inheritance.

Domain controllers group policy refresh interval:

By default, domain controller group policies are update in the background every 5 minutes.

Loopback Policy

Windows Server: Understand “User Group Policy Loopback Processing Mode”

Refer the below Link.

Group Policy Object (GPO) is a set of rules for users and computers, thus the policies for computers will be applied to computers and the polices for users will be applied to users.

Let’s assume that you have two organizational units in your domain.

OU – TSSERVERS

OU – Support

In OU – TSSERVERS units, there are computer accounts and in the OU-Support units are user’s accounts.

In OU-TSSERVER, you created and configured a new GPO, so there are policies for

Computer Configuration

User Configuration

In OU-Support, you created and configured a new GPO. So, there are polices for :

Computer Configurations

User Configurations

When a user belonging to OU-Support logs on a server that belongs to the OU-TSSERVER, what happens?

Apples:

Computer Configuration -> the configuration created in the GPO linked to OU-TSSERVER.

User Configuration -> The configuration created in GPO linked to OU-Support.

This is the default settings:

Now we are finally going to learn about User Group Policy Loopback Processing Mode.

When configuring the Policy Loopback Processing Mode, you can choose two different options, Replace and Merge.

Replace Mode:

When you define the “User Group Loopback Processing Mode”, to “Replace” on the GPO linked to the OU-TSSERVER.

Applies:

Computer Configuration -> The Configuration created in GPO linked to OU-TSSERVER.

User Configuration -> The Configuration created in GPO linked to OU-TSSERVER (This is the difference in replace mode)

Merge Mode:

When you defined the “User Group Loopback Mode”, to “Merge” on the GPO linked to the OU-TSSERVER.

Applies:

Computer Configuration -> The configuration created in GPO linked to OU-TSSERVER.

User Configuration -> The configuration created in GPO linked to OU-TSSERVER.

And

User Configuration -> The Configuration created in GPO linked to OU-Support.

 (This is the difference in Merge Mode).

Note: In case of conflict, the user polices from OU-TSSERVERS have precedence, because the computer’s GPO is processed after the user’s GPOs, they have precedence if any of the settings conflict.

Why is this configuration important to me?

Use this configuration if you have users in your domain whose folders are redirected through policy, but you don’t want that redirect to occur when users log on through Terminal Services.
You need to enable this policy setting using the Replace mode on GPO linked to OU, where the Terminal Server's computer accounts are (without folder redirection enabled). When users log on to Terminal Servers, the policy folder redirection is not applied.

To enable “Loopback processing Mode”

Using Group Policy Management Console, edit the GPO you desire, expand Computer Configuration\Policies\Administrative Templates\System\Group Policy,
and then double-click User Group Policy Loopback Processing Mode.
Then select the appropriate option (Replace or Merge).
