Changing SID on Windows Server 2019: Step-by-Step Guide #

Changing the Security Identifier (SID) on a Windows Server 2019 is a crucial task that ensures the uniqueness of the server’s identity in a network. To change the SID, follow these step-by-step instructions:

  1. Create a System Image Backup: Before proceeding with any changes, it is highly recommended to create a system image backup of your Windows Server 2019. This will serve as a fail-safe solution in case any issues arise during the SID change process. Use reliable backup software or the built-in Windows Server Backup feature to create a complete system image.

  2. Prepare for SID Change: To prepare for the SID change, ensure you have a bootable Windows Server 2019 installation media or an ISO file. Insert the media or mount the ISO and restart the server. Boot from the installation media and access the Windows Setup screen. Press Shift + F10 to open the command prompt.

  3. Change the SID: In the command prompt, type regedit to open the Registry Editor. Navigate to HKEY_LOCAL_MACHINESYSTEMSetup and delete the CloneTag value. Close the Registry Editor and return to the command prompt. Run the following command: sysprep /generalize /oobe /shutdown. This will generalize the server, remove the SID, and shut it down. Once the server is powered off, you can boot it up, and it will generate a new SID during the startup process.
