RDP Authentication error about windows

[CallyHam]

it can, i have now fixed the issue on my main pc too, it was a uac related thing

Very strange!! I can connect to all of those versions just fine (using Microsoft RDP for Android on my phone, havent tested it with an actual Windows computer).

During installation I modify a registry setting to allow RDP users to login even if the password for the useraccount (Docker) is empty. This works fine using the RDP client for Android, but maybe the Windows client does not allow it even if the guest allows it.

So my first suggestion would be to set a password for the Docker user account and see if that solves it.

i have tried setting a password and it seems to have no effect, i will try connecting from a mobile device and see how that goes
Update: to my surprise it works perfectly fine from my phone, i will also try another windows machine to double check if its actually an issue with windows itself

I just tried it from a real Win11 computer to a Win11 container, and it worked without problems (even with the blank password).

So it seems not a general problem with the container, as it works from your phone and my phone+computer. So it must be some kind of misconfiguration on your LTSC 2021 PC. Would be interesting to know if it just cannot connect to the container or cannot connect to any computer at all. In the last case there is not much I can do.

ah yeah same thing trying to connect to a win10 laptop on my network, no idea whats wrong here but its not a problem with the container, even weirder: i can connect from said laptop to my pc, but not the other way

But can this laptop connect to the container? If so, I will close the issue because it is not something I can fix.
