Understanding Recent Patch Tuesday Bugs in Windows Server 2025
Patch Tuesday releases from Microsoft are known for occasionally introducing bugs. This is expected due to the vast diversity of hardware and software that spans a multitude of devices worldwide. Recently, an issue has surfaced among Windows Server 2025 installations that highlights this ongoing challenge.
Active Directory Sync Issues Identified
According to an update posted on the Windows Release Health dashboard, Microsoft is monitoring a disruption related to Active Directory (AD).Organizations utilizing Active Directory directory synchronization, commonly referred to as DirSync, for their on-premises Active Directory Domain Services (AD DS) may experience failures during synchronization. This problem arises specifically when the size of the AD security group surpasses 10, 000 members.
Effects of the Synchronization Bug
The synchronization issue stems from September’s Patch Tuesday updates, particularly for those who have installed the KB5065426 update or later versions. It is noteworthy that this bug primarily affects larger organizations with significant member counts in their AD groups, thus smaller businesses might escape its impact. Nevertheless, the potential repercussions are significant, especially as large enterprises encounter synchronization failures that could disrupt vital operations.
Temporary Workaround and Future Solutions
While Microsoft has yet to provide a definitive fix, it has suggested a temporary workaround for those affected. IT administrators can adjust the Windows Registry following these steps:
- Path: Computer\HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Policies\Microsoft\FeatureManagement\Overrides
- Name: 2362988687
- Type: REG_DWORD
- Value: 0
Microsoft has indicated that a more stable patch is forthcoming in a “future Windows update, ”although the specific timing remains uncertain. For those impacted, a prompt resolution is crucial, as synchronization failures in Active Directory can cascade into various operational challenges. In the interim, IT administrators are advised to consult the Windows Registry guidance to ensure safe execution of the workaround until the official fix is deployed.
