Windows 2008R2 and SCCM 2007 SP2 - Pt2 - Install SCCM 2007 SP2

Continuing the previous article, once you have all the prerequisites in place, you are ready for the installation of SCCM 2007 SP2.

Extend the active directory schema
First, you have to extend the Active Directory Schema. The best way to do this is to log on to on the domain controller that holds the schema master role and start an elevated dos prompt. Then run the following program from the SCCM 2007 SP2 cd (or files on a share):


If you encounter errors like these:

<09-11-2010 17:53:11> Modifying Active Directory Schema - with SMS extensions.
<09-11-2010 17:53:11> DS Root:CN=Schema,CN=Configuration,DC=stpauls,DC=qld,DC=edu,DC=au
<09-11-2010 17:53:11> Failed to create attribute cn=MS-SMS-Site-Code.  Error code = 8224.
<09-11-2010 17:53:11> Failed to create attribute cn=mS-SMS-Assignment-Site-Code.  Error code = 8224.
<09-11-2010 17:53:12> Failed to extend the Active Directory schema.

.. you probably have some replication issues to deal with first. Or, in my case, the domain had one or more child domains and those domain controllers were offline. Make sure they are online and reachable.

Add the computer account to the System container

  • On the domaincontroller, start Active Directory Users and Computers.
  • Make sure you have advanced features enabled (View, Advanced Features)
  • Rightclick the “System” container, properties
  • Security, Add, Object Types, enable Computers + OK, type in your SCCM computername and click OK
  • Make sure your SCCM computername is selected, then click full control, followed by advanced
  • Locate your SCCM computeraccount, select it and click on Edit, set Apply to to “This Object and all descendant objects”, OK, OK

Install SCCM

  • From te splash screen run the “Run the prerequisite check”
  • If you’ve followed my previous article and you’ve installed SQL, enter your servername (my case: SCCM01) in the first two fields and press OK
  • Checks will run and if all goes well you’ll see “All required prerequisite tests have completed successfully”
  • On the splash screen click on “Install - Configuration Manager 2007 SP2”
  • Next, Next, I accept + Next, Custom Settings + Next, Primary Site + Next, Next, …. Next, Enter a (3 cypher/letter) site code and a description (”VL3” and “Test VLAN 3” in my case) for the site and on the next screen select Mixed Mode, unless you have a Public Key Infrastructure in place and configured for SCCM.
  • Keep all the rest of de settings default until you reach the “Updated Prerequisite Components” screen. Select the “Check for updates …” and click Next. Select a folder to download the updates (e.g. e:\downloads\) and hit Next. Some updates will be downloaded.
  • Once downloaded, you come to the Settings Summary. Press Next and another prerequisite check will run. If all goes well, press “Begin Install”.
  • Press Finish.
  • Reboot the computer and SCCM 2007 SP2 is ready for configuration
