Prerequisites for System Center Configuration Manager 2012 R2

Before you start deploying System Center Configuration Manager, you must make sure that your infrastructure meets all of the prerequisites. What follows is a list and a step-by-step guide that shows you how to meet these prerequisites.

Creating the System Management container

When the Active Directory schema is extended, the System Management container in Active Directory is not created by default. The container has to be created in all Active Directory domains that contain a primary site server or a secondary site server that publishes site information to Active Directory. In order to create the System Management container, take a look at the following steps:

1. You have to log on to your Domain Controller and open ADSI Edit. You can also do this from any other machine that has ADSI Edit installed on it and connect to the Domain Controller. The account that you use to connect to the Domain Controller must have permissions to modify objects in ADSI Edit. You can open ADSI Edit from Server Manager Console, from the Control Panel\System and Security\Administrative Tools locations or by opening Run under the Start icon and typing adsiedit.msc:
   
2. Right-click on ADSI Edit and click on Connect to…:
   
3. In the Connection Settings window, make sure that the Name field is set to Default naming context. Leave everything else as it is and click on OK:
   
4. In the ADSI Edit console, expand Default naming context in the folder pane, right-click on CN=System, click on New, and then click on Object…:
   
5. When the Create Object window appears, select container and click on Next:
   
6. Enter System Management in the Value textbox and click on Next to finish:
   

With this, the System Management container is created in Active Directory. Next, we have to join the site server to the Active Directory domain and give computer account permissions to the site server to publish the site information to the container. A primary site server computer account must have full control permissions on the System Management container. To do this, perform the following steps:

1. Open the Active Directory Users and Computers console or open Run under the Start icon and type dsa.msc.
2. Navigate to the System Management container, right-click on it, and select Delegate Control…. When you click on Delegate Control…, a wizard starts, which guides you through the process:
   
3. In the first window, just click on Next.
4. In the second window, click on Add…:
   
5. When a new window appears, go to Object Types and make sure that Computers is checked:
   
6. Then, add your primary site server's computer account and click on OK:
   
7. In the next window, select Create a custom task to delegate:
   
8. Select This folder, existing objects in this folder, and creation of new objects in this folder and click on Next:
   
9. In the next window, select all the three options under Show these permissions and select Full Control under Permissions. Then, click on Next:
   

We have now delegated full permissions to the primary site server's computer account on the System Management container. To find out how to create the System Management container in a different way, check this link:
