Error "An authentication error has occurred (Code: 0x800706be)" when trying to use Remote Desktop to connect in Windows 10

I saw the same article for Windows 11, however I experience this problem on Windows 10. What did I do

  • install Azure Remote Desktop on my Windows 10 machine (latest update)

  • logged into my company workspace using my company MS account

  • tried to login to my remote VM

  • I get an error message - An authentication error has occurred (Code: 0x800706be)

  • cherry on top, this is my personal notebook. On my office computer I can access the VM just fine. Same installation of Windows and Azure Remote Desktop

what can be wrong?

Hi,

thanks for answers, however neither did sort out the problems for me. What I tried so far:
- registry cleanup with CCleaner
- sfc /scannow
- using various windows troubleshooters that might have at least some relevance to remote desktop connection
- removing computer from domain
- defining explicit outbound rule for remote desktop in Windows Firewall
- updating windows from 21H1 to 21H2

I am afraid that only formatting the disc and installing windows again have some potential of sorting the situation out. However it is ridiculous solution
