Error "An authentication error has occurred (Code: 0x800706be)" when trying to use Remote Desktop to connect in Windows 11.

Question

I get the following error in Windows 11 when I try to connect to a certain computer with Remote Desktop. It was working fine before I accidentally selected delete credentials. Now it refuses to connect and not even a System Restore could fix the problem. My laptop and other PC can connect to the remote computer without any problems. What can I do to fix this please? Strangely enough Remote Desktop works fine when creating a new user account on the affected machine and using it under the new user account.

Answer 1

i have same issuse in win11 after update in 29.04.2022,
i resolved with
”sfc /scannow”

C:\Windows\system32>sfc /scannow

Beginning system scan. This process will take some time.

Beginning verification phase of system scan.
Verification 100% complete.

Windows Resource Protection found corrupt files and successfully repaired them.

Answer 2

sfc/scannow didn't work for me (win 10 pro 21H2).

I can affirm the issue is related to MicroSoft's mstsc client.

3rd party (non-microsoft) remote desktop tools DO work on the same computer to connect to the same server, using the same account/credentials.

Answer 3

This issue occurs when running Remote Desktop elevated as a different user, and that different user account has never logged in to the workstation (no complete local profile). I've submitted a bug report to Microsoft, please help me get some traction on it with an upvote! https://aka.ms/AAkm0o2
