RDP connection drops 30 seconds before user login, why is that?

Question

System administration

Good Friday friends!

The essence of the problem:
We have an RDP connection with authorization on the GUI, that is, on the welcome screen. After connecting, if you do not enter the system - the connection is reset exactly after 30 seconds.

How to win? Friday's brain doesn't cook... I rummaged through everything.

Answer 1

The solution was found:
On the server (and on regular Windows if it is not a server RDP) by default there is a 30-second timeout for GUI authorization, you can disable it like this:
1. Go to: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Controll\TerminalServer\WinStations\ RDP-Tcp
2/ Create a DWORD string value
3/ Let's name it: LogonTimeout (DWORD)
4/ Set the value to 3600 minutes, for example.
5/ Reboot the server
Done. Connection no longer resets after 30 seconds.

maybe the dog rummaged around here?
