When I road tested the new Server 2025 over RDP I came across an interesting problem which only occurred when I tried to connect from a windows desktop using mRemoteNg. If I left the server for an hour or so I got a splash screen without any login box. I wasnt really expecting one as it was an RDP session but I could do nothing to move forward with the login. After restarting the server several times to clear this problem I looked for a better solution.
I will say that connecting from my iPad I did not get this problem so I looked for problems with mRemoteNg, but after trying a few different PC RDP programs I got the same result.
The problem lies in a setting called “Continuous Network Detect” and is a problem because of a recent windows update.
To solve this you need to use GPO Group policy edit.
Computer Configuration -> Policies -> Administrative Templates -> Windows Components -> Remote Desktop Services -> Remote Desktop Session Host -> Connections
Under ‘Select network detection on the server’ set ‘Select Network Detect Level’ to ‘Turn off Continuous Network Detect’
Also turn off…..network detect, its a dropdown in the select network level setting.
