Hello,
Thank you for posting in the Microsoft community forum.
Based on your problem description and label, the security issue you are experiencing is most likely due to Windows Server 2012 reaching the end of support on October 10, 2023. After this date, it will no longer receive security updates, non-security updates, bug fixes, or technical support.
You might consider upgrading to a newer version of Windows Server. If you can't upgrade immediately, you can purchase Extended Security Update (ESU) for Windows Server 2012. This will provide security updates for up to three years.
