June Windows Server upgrades disrupt Microsoft 365 Defender functionality

Microsoft confirmed that a Windows Server update released last month on Patch Tuesday caused some Microsoft 365 Defender features that use the Network Data Reporting Service to stop working.

Redmond describes Microsoft 365 Defender (now known as Defender XDR) as an enterprise pre- and post-breach security suite that helps orchestrate detection, prevention, investigation and response across an organization's endpoints, identities, email and applications. "Devices running Windows Server updates released on June 11, 2024 may experience issues with Microsoft 365 Defender," the company explained on the Windows Server Status Dashboard.

"The Network Discovery and Response (NDR) service may experience issues that may disrupt network data."

This known issue (first discovered on Friday) only affects Windows Server 2022 systems and will also cause additional Defender features that use the NDR service to collect data (such as incident response and device inventory) to stop working properly, and will not affect other features (such as vulnerability management and device inventory). Cloud service applications) are not affected. Admins can see if systems in their Windows networks are affected by checking the Service health page in the Microsoft 365 admin center for new alerts.

Redmond said engineers are working on a fix and will provide more details in an upcoming update. Other problems with recent Windows Server updates
