Remote Desktop disconnects after 65 seconds
What broke
The March 2025 update introduced a very specific kind of torture: RDP sessions that work perfectly for exactly 65 seconds, then disconnect. UDP-based Remote Desktop connections from Windows 11 24H2 to Windows Server 2016 or earlier would drop like clockwork just over a minute in. IT admins managing older servers got to experience the joy of reconnecting every minute while trying to troubleshoot why their connections kept dropping. The fix took over two weeks to arrive.
