The September update for Windows 11 and Windows Server is causing significant issues with Remote Desktop Services (RDS). Users report that connections drop after several hours of operation, preventing new logins and failing to log out existing sessions.
Affected IT administrators note that system tools like the RDS Licensing Diagnoser and File Explorer stop responding. In many cases, the only way to restore access is to perform a hard reboot of the server, followed by the uninstallation of the update.
For physical servers deployed on the public internet, the loss of RDP access is critical. Administrators are forced to rely on IPMI interfaces, such as iLO or XCC, to manage the hardware directly when standard remote access fails.
Microsoft has acknowledged the issue but has not yet provided a permanent fix. For virtualized environments, the company suggests shutting down and deallocating the server to restore connectivity while they work on a permanent resolution.
