SCCM 2012 R2 PART 2 – Installing Prerequisites for SCCM 2012 R2

In this part, we will perform:

  1. Add a System Management Container
  2. Add Permissions for the Site Server to be able to publish site information to the container.
  3. Extend the Active Directory Schema
  4. Install all the pre-requisites for SCCM 2012 R2

Please refer to the following article for creating the Domain Controller:

1/ Add a System Management Container

Once the Domain Controller is in place, let’s create the required container.

In Server Manager, Click Tools, ADSIEdit

Right-click ADSIEdit and choose Connect to…

Without changing anything, click OK.

Drill down the Default Naming Context to CN=Systems and right-click on it, create a new Object.

Select Container class.

Enter value as System Management and click Next.

Click Finish.


2/ Add Permissions for the Site Server to be able to publish site information to the container.

After creating the Container, we need to give the Site Server Computer account FULL permission to be able to publish information to the container.

Launch dsa.msc or use Server Manager to open Active Directory Users and Computers.

View -> Advanced Features

Expand Systems and right-click on System Management, Choose Delegate Control.

Now we will add Full Permission for the Primary Site Server account to access this container.

Click Add

Click Object Types

Checkmark on Computers and click OK.

Type SCCM and click Check Name. Note: (I have already create a new Computer account called SCCM in Active Directory Users and Computers for this to happen. I have not actually deployed the SCCM server yet; just a Computer account was created).

Click Next

Click Create a custom task to delegate and click Next

Choose “This folder, existing objects in this folder, and creation of new objects in this folder” and click Next.

Make sure to check on General, Property-specific, and Creation/deletion of specific child objects. From there, click Full Control. Click Next.

Click Finish.

We have successfully assigned proper permissions for the Site server computer account to access the System Management container.

3/ Extend Active Directory Schema

Browse to the SCCM DVD under this path: SMSSETUP\BIN\X64. Locate the file extadsch.exe.

Launch CMD and run that file as Administrator.

Make sure it is successful.

To verify success, open C:\ ExtADSch.txt and read the contents. Ensure it says successfully extended the Active Directory Schema.


4/ Installing Pre-requisites for SCCM

If you have not already done so, please deploy a Windows 2012 R2 Server and call it SCCM. Join the computer to the DALARIS.LOCAL domain. Its TCP/IP settings are like this

Server name and domain member is shown as below:

Now we will install Web Server (IIS) onto the SCCM server. Launch Server Manager, Choose Add Roles and Features.

Click Add Features when prompted.

Click Next.

Before clicking Install, click on Specify an alternate source path. Point the path to E:\Sources\sxs, where E: contains the Windows 2012 R2 installation source. After that, click Install.

Once installation has succeeded, click Close.

5/ Installing the Windows ADK. This is a set of tools that allow the administrator to assess, edit, manage, and deploy operating systems to new computers. Download the newest version (8.1) and install.

Click on Install. As you can see, the installation file is only approximately 1.6MB. But the space requirement is 3.1GB. So definitely, there is going to be some download involved. After clicking Install, you can go for a coffee and come back 15 minutes later.

Click OK when done

That’s it.
