In this post we will see the steps for Installing Prerequisites for Configuration Manager 2012 R2 and we will also see the steps to create a system container, assign permissions for SCCM server on the container and extend the active directory schema. In my previous post I talked about the new features of system center 2012 R2 configuration manager and the system requirements for installing configuration manager 2012 R2. Before you can install Configuration Manager you should extend your Active Directory and give your SCCM server rights to create objects under the system container in AD.

Does Configuration Manager creates System Container automatically ?

Configuration Manager does not automatically create the System Management container in Active Directory Domain Services when the schema is extended. The container must be created one time for each domain that includes a Configuration Manager primary site server or secondary site server that publishes site information to Active Directory Domain Services.

Creating the System Management Container

We will first create the system management container and we will assign the SCCM server permissions to create objects under the system container. The domain controller is running on windows server 2012 R2 Datacenter edition operating system. To create a container log on to the Domain controller with administrator account, click on Server Manager, Tools, click on ADSI Edit.

Right click ADSI Edit and click on Connect to. On the Connection Settings window, the naming context should be Default naming context. Do not change anything here, click on OK.

In the ADSI Edit Console, expand the Default Naming Context, right click CN=System, click on New and create an Object.

On the Create Object windows, select the class as container and click on Next.

Provide the value as System Management. Click on Next and click on Finish to close the wizard.

Now that we have created the system management container, we must grant the site server’s computer account the permissions that are required to publish site information to the container. The primary site server computer account must be granted Full Control permissions to the System Management container and all its child objects. Click on Server Manager, click on Tools, click on Active Directory Users and Computers. Click on View and click Advanced Features. Expand System, right click System Management and click on Delegate Control.

The primary site server computer account must be granted Full Control permissions to the System Management container. Click on Add, on select users,computers or groups window click on Object Types and check for Computers as object types. Click on OK. Type the name of the primary site server computer account and click on OK.

You must see the primary site server computer account listed under the users or groups. Click on Next.

On the Tasks to Delegate page, click on Create a custom task to delegate. Click on Next.

On the Active Directory Object Type window, select the option This folder, existing objects in this folder and creation of new objects in this folder. Click on Next.

We need to select the permissions to delegate, choose General, Property Specific and Creation/deletion of specific child objects. Under the permissions, click on Full Control. when you check the box for Full Control all the other permissions gets checked automatically. Click on Next and click on Finish to close the wizard. We have delegated full permissions to primary site server computer account on System Management container.

Extending Active Directory Schema

To extend the Active Directory Schema using extadsh.exe utility, locate the extadsh.exe which can be found in \SMSSETUP\BIN\X64 of the configuration manager setup DVD. Hold the shift key on your keyboard and right click extadsh.exe and click on Copy as Path.

Launch the command prompt. Right click and click paste and hit enter. You should see the line Successfully extended the Active Directory Schema.

To verify whether schema extension was successful, open the log file extadsch.log located in the root of the system drive. You should see the line “Successfully extended the Active Directory Schema”.
