Microsoft has confirmed that Windows Server updates from last month's Patch Tuesday break some Microsoft 365 Defender features that use the network data reporting service.
"Devices which have installed Windows Server updates released June 11, 2024 might experience problems with Microsoft 365 Defender," the company explained on the Windows Server health dashboard.
The known issue only affects Windows Server 2022 systems and will also prevent additional Defender features relying on the NDR service to collect data to work correctly, while others will be unaffected.
The same month, Microsoft also fixed known issues that broke VPN connections across client and server platforms, triggered domain controller reboots, and caused NTLM authentication failures after installing April's Windows Server security updates.
