@xorel There was also a reported issue with RDP session drops on Windows Server 2025. I was able to reproduce it locally — after VM startup and establishing an RDP connection, the session gets disconnected after a short period of time and reconnects automatically a few seconds later. This behavior has not been observed on other Windows Server versions.

@roamingengineer311 , could it be related to the known bug fixed in that KB?

[Remote Desktop] Fixed: This update addresses an issue where Remote Desktop sessions were freezing shortly after connection. With this issue, mouse and keyboard input became unresponsive within the session, requiring you to disconnect and reconnect.
So one needs to check if that update is installed.

Other possible causes: 1 and 2

In any case it looks more like Windows Server 2025 or RDP client issue than OpenNebula context.
