Hello Patrick Archibald, Thank you for posting in Q&A forum. In a Windows 11 multi-session environment, if you have RSAT installed and you are building an Azure virtual machine (VM) from a shared gallery image that has been processed by Sysprep, but you encounter an error every time you try to open the Group Policy Management Console and extend the domain via gpmc.msc. Here are some possible workarounds:
- Group Policy components are not fully installed or are incorrectly configured: Although RSAT is installed, some component configurations can be lost or corrupted during the Sysprep process. Rerun the RSAT installation to ensure that all required Group Policy management components are properly installed and configured. Also make sure you are using the latest version of the RSAT tool. Sometimes, an update tool can fix a known issue.
- Group Policy Cache Issues: Sometimes, the local Group Policy cache may need to be updated or rebuilt on the first launch after sysprep. Group Policy can be forced to refresh by running the 'gpupdate /force' command.
- Check the event logs: Open the Windows Event Viewer and look at the Application and System logs for information related to GPMC errors. This may provide more details about the error.
- Update Windows: Make sure your win11 operating system is up to date with the latest updates and patches. I hope the information above is helpful. If you have any question or concern, please feel free to let us know. Best Regards, Daisy Zhou
