RDP connection not possible and RDS-Virtualization role comes back after restart

Hello everyone,

I have here an Windows Server 2022 Standard 21H2 (Build 20348.4052) (essentials) with the newest updates. This is the Domain Controller. Hyper-V is installed with one VM. The VM is a terminal server. In the past I have tried to install the terminal server on the Hyper-V Server. To do so I have installed all kind of remotdesktop roles. This was stupid of me. Especially it does not work on a DC.

I want to connect as administrator by RDP (mstsc) to the server but it does not work anymore since I have installed all these roles and features. No other users are connected. I can still connect to the VM.

In one situation I was able to connect to the server but after entering the password I have received the error 0x808 (0x101) that there is no licence server for remote desktop available. 

I have now removed all roles related to the terminal server and the rdp which I have installed. But I can not uninstall RDS-Virtualization. After uninstalling it comes back when I perform a restart. I have already tried Uninstall-WindowsFeature -Name RDS-Virtualization -Remove

In the server manager appears a menu item about remote desktop services. But there is written that no connection broker server is in the pool. The submenu server lists my DC.

I have found in the eventmanager a error related to the uninstalling process 0x80070057 wrong parameter But I do not have more information.

DISM /RestoreHealth and sfc /scannow did not find any problems.

I am not using VDI but is maybe the Hyper-V reinstalling the role after the restart?

Do I need to uninstall the role to make RDP working again or could be there other reasons?

Do you know where I find a detailed log about the problems about uninstalling the role and maybe the installing?

Do you have any idea how I can find out more about the problem?

Thank you!
