  • #1: yes, if you do no longer want to manage them
    #2: ccmsetup.exe /uninstall will remove them. You can trigger that remotely (e.g. psexec.exe)
    #3: run ConfigMgr setup and select the option to uninstall
    #4: yes if there are no other ConfigMgr sites publishing to this forest
    #5: basically if no more ConfigMg services are running

    Why would you uninstall and 1 week later decide to install it back?

    If that could be the case then i would suggest to keep the clients installed for the whole week instead of uninstalling them. The network traffic involved to install the client can be high (depending on your network connection and number of clients).

    The System Management container can be easily recreated that won't be an issue if you delete it. It will be repopulated within seconds as soon as you reinstall and restore your server.

  • Hi,

    We are facing a issue in our environment due to that we need to go for uninstallation and reinstallation.

    The below is the issue

  • If you are sure about installing the server back and restoring the backup then keep the clients on your workstations.

    As soon as CM is operationnal again they will be able to communicate with your server.

  • How many clients will you be managing in total then? A CAS will not be needed most likely, so you should consider using a standalone primary instead.
    There's no need to delete the System Management container itself then (but the content; all entries that belong to the uninstalled site). You can also leave the clients installed then.

  • Thanks Torsten,

    We will manage approx 150 clients. Our datacenters are in two diffrent country.  Our SCCM CAS and primary site servers are in US. Out of 150 client machines, 60 client machines are in UK and 90 client machines are in US. During patching activity UK machines take more time to download patches and installed from Distribution Point.  that is why we are planning to install new Distribution point in UK in CAS site heirechy. Please let me know If we can manage it by standalone primary site alone?

    Once again than you very much for your valuable inputs here:)

  • A standalone primary can handle up to 100.000 clients, so a CAS would be overkill in your scenario.
