Microsoft shares workaround for Windows domain login issues

Microsoft confirms September 2026 Windows updates trigger domain trust failures via Machine Identity Isolation and shares a workaround for Windows 11 enterprises.

Microsoft confirmed the September 2026 security updates (KB5124008 for Windows 11 24H2/25H2, KB5124012 for 26H1) cause Windows to honor Machine Identity Isolation enforcement settings, breaking domain trust on systems not connected to Windows Server 2025 domain controllers. Admins report valid credentials failing with domain trust and credential errors. The workaround requires disabling Machine Identity Isolation via the same management method that enabled it (Intune, group policy, or registry) and resetting the secure channel with Test-ComputerSecureChannel. Microsoft previously shipped out-of-band fixes for Remote Desktop, Hyper-V, and USB audio issues from the same updates.

Microsoft Confirms Remote Desktop Services Might Stop Working Following Sept. 2026 Security Update

Microsoft's September 2026 Patch Tuesday updates (KB5124008) can break Remote Desktop Services, causing RDP failures and freezes across Windows clients and servers.

Microsoft confirmed its September 2026 security updates, including KB5124008 for Windows 11 24H2/25H2, introduced a reliability regression where RDP connections fail after several minutes and servers hang at the 'Please wait for the Remote Desktop Configuration' screen. MMC, RDS Licensing Diagnoser, File Explorer, and the Windows Update settings page may also stop responding. The issue affects Windows 10/11 clients and Windows Server 2012 through 2025; Microsoft marked it Mitigated on September 11 and is developing a permanent fix, with VM restart offered as a temporary workaround.
