How to Uninstall SCCM Primary Site

In this post we will see how to uninstall SCCM primary site. Sometimes you want to try new things because you want to learn something out of it. I would like to post a quote made by Walt Disney here. “We keep moving forward, opening new doors, and doing new things, because we’re curious and curiosity keeps leading us down new paths”.

The first question you would probably ask is why should one uninstall SCCM primary site ?. There could be a situation where you would want to setup new site completely. Or probably get rid of the old primary site that has got tons of issues or it could be something else. Well I have got a big lab setup with just a single SCCM primary site. Now that I wanted to create a new setup, i thought of deleting all the virtual machines. But then, that would be so easy to do. So i thought why not try out uninstall configuration manager site option.

Long back I published a post on performing SCCM site reset. Note that SCCM site reset is different from uninstalling your configuration manager site. Though both options are seen on same screen, however one should use them wisely. If you are looking to perform SCCM Configuration manager site reset, this post will help you. In this post I will cover the steps to uninstall SCCM primary site.

Before you Uninstall SCCM Primary Site

Since you have decided to uninstall SCCM primary site, there are few things that i would like to add here. What if you have a hierarchy with multiple sites ?. Will you decommission primary site server directly ?. The answer is No. In such cases the sequence of removal is important. Remember that if your hierarchy has multiple sites, you must start by uninstalling the sites at the bottom of the hierarchy and then move upward.

  1. First of all remove secondary sites attached to primary sites.
  2. Next remove primary sites. We will see how to do that in this post.
  3. After all the primary sites are removed, you can uninstall the central administrations site.

As mentioned earlier, i have got just one primary site in my lab setup. Do not worry about what roles are installed on site server, we are just going to uninstall configuration manager primary site using simple steps.

  1. If I’m going to uninstall my only primary site and perform a clean reinstall, so I need to uninstall the agents that have been deployed within my environment first (or at all)?

  2. Hi I am getting error to uninstall CAS after failed installation attempt. The uninstallation process is failing with “Cannot continue uninstall, Setup failed to get the number of attached primary sites”. Their is no primary site this is first cas server. Please help. Thanks

  3. I just found “Windows Deployment Services” as an installed Server role. I assume SCCM installed it automatically when I chose that option. I have removed and restarted. Now I just have the 2 services SMS Agent host and SMS_Notification_server. I copied ccmsetup.exe from installation DVD and tried running ccmsetup.exe /uninstall but both of those services are still there. Is there another way to cleanly remove it?

  4. I found the following services still on the server and running:
    Windows deployment services server
    SMS Agent Host
    SMS_Notification_server – not running

    I disabled the two and restarted the server and it eliminated the errors, but now I would like to delete the directories
    C:\Program Files\Microsoft Configuration Manager and C:\Program Files\SMS_CCM. I am assuming I would get more errors since the one service, SMS Agent Host points to a file in one. I guess I will have to modify the registery. Any other options to get these to properly uninstall?

  5. I followed the above instructions and restarted the server. I received the following errors:

    Log Name: System
    Source: Server
    Event ID: 2511
    Level: Warning
    Description:
    The server service was unable to recreate the share AdminUIContentPayload because the directory C:\Program Files\Microsoft Configuration Manager\AdminUIContentPayload no longer exists. Please run “net share AdminUIContentPayload /delete” to delete the share, or recreate the directory C:\Program Files\Microsoft Configuration Manager\AdminUIContentPayload.

    I followed ran the commands to delete the share and found 3 other shares that pointed to directories under C:\Program Files\Microsoft Configuration Manager and stopped sharing them.

    Also received these errors:

    Log Name: Application

    Event ID: 259

  6. I have a scenario where i have mistakenly installed CAS instead of a Primary site which led me to have to uninstall CAS using the method above. Is there anything I need to do in relation to the prerequisites (SQL, WSUS) before reinstalling as a Primary site? or would it be better to blow away the VM and start from scratch?
    Thanks

  7. This is a great site – all actions are very clearly written and very accurate. Well done to you Mr Desai.
