The ConfigMgr server, after extending the Active Directory schema, is able to save core configuration data in the Active Directory database inside the System Management container. Thanks to these pieces of information, clients are able to find the assigned ConfigMgr server and establish connection with it. Any changes made to the management point role are also saved and stored in the Active Directory database.
There are two ways of the System Management container creation:
The container can be created manually and grant permissions to the ConfigMgr computer account
ConfigMgr creates it by itself thanks to the granted permissions
The presence of this container is not obligatory to go through the ConfigMgr installation process. The container, as well as permissions, might be created later after the server is installed.
To manually create the System Management container using the Active Directory Users and Computers console, follow these steps:
Run the console, highlight the System container, right-click on it, and choose Properties:
System container in Active Directory Users and Computers console
On the Security tab, click on Add... to add a computer account for the ConfigMgr server:
Properties of System container
By default, the system does not show computer accounts when adding permissions. To see them, we need to check Computers in the Object Types... section and click on OK:
Adding computer accounts to searchable objects in Active Directory
We fill in the computer name, and to ensure that we typed it correctly, we click on Check Names and then we click on OK:
Pointing ConfigMgr computer account
The next step is to add permissions to the computer AD account. Highlight the computer account visible on the Security tab and click on Advanced:
Choosing a computer account for granting permissions
Windows Advanced Security Settings for System appears. Highlight the ConfigMgr computer account and choose Edit:
Editing of permissions for the System container
On the Permission Entry for System tab, check Full control and change the Applies to section to This object and all descendant objects:
Configuring permissions for a computer account
After granting permissions, click on OK thrice. At this point, the environment is prepared for ConfigMgr to create the System Management container on its own and save the configuration data in there.
