SCCM Site Reset

Let’s learn more details about Site Reset options in Configuration Manager world. This is the step by step guide to Perform ConfigMgr Site Reset. I have seen many scenarios where the reset operation helped to fix some “weird issues” with SCCM infrastructure.

What is Configuration Manager Site Reset Means?

You can initiate ConfigMgr site reset from Primary or CAS server. I don’t think we can initiate a SCCM site reset from secondary server. Let’s check the actions performed on the server side as part of Site Reset:

  • Reapplies the default ConfigMgr file and registry permissions
    • Restores the following objects
      • The SMS or NAL registry keys, and any default subkeys under these keys.
      • The ConfigMgr file directory tree, and any default files or sub directories in this file directory tree.
  • Reinstalls all site components and all site system roles at the site

NOTE! – A site reset does not reset access permissions to non-ConfigMgr objects. I don’t see any major impact performing the site reset. The site reset is mainly a straight forward process.

Permission Requirements for Site Reset?

My recommendation is use the account which you used to install the primary or CAS server to perform site reset. You can use similar accounts with same level of access rights. More details User & Computer Access Rights Requirements.
