Credentials supplied to the package were not recognized when connecting to some Windows Server Machines

DGIWD 251

Hello, I am trying to connect in RDP several machines under Windows Server 2019 but when I log-on (with correct user/password of course), it denies me with:

"An authentication error has occurred. The credentials supplied to the package were not recognized".

I am in Windows 10 pro connected to an AzureAD domain.

I can log in to these servers from an another machine in Windows 10 but not logged into the domain.

I search on Google with no luck.

Has anyone an idea ?

Thanks.

Thanks - hadn't see the error until a user got a new Windows 11 computer. Other users with Windows 11 didn't have the issue. Thanks for providing this solution: .\username

I finally got it to work:

I simple added the prefix

AzureAD\

before my username... Go figure out why...

Another workaround for this is to use .\UserName if the user is locally defined. I had this problem with an AWS VM and this post reminded me that you sometimes need to have the machine qualifier for the user.

Worked! It's always something like this. btw, the backslash is very important. Not forward slash.

Hello,

Yes, I am just trying to connect via RDP to the remote server. I am trying to connect via mstsc, with any of the remote user it does not work.

I don't understand the link you provided me. It is about OpsMgr, it talks about agents, certification servers... I never heard of it before. Why it is relevant to my situation ? I never installed/configured that sort of things on my server.

I was able to login from my computer to this server and one day it just doesn't work anymore from my computer (but from others, it still does). Since it has been a months since I did not login, I can't tell you what I have done on my personal computer which could implies such errors.

Hei, @DGIWD
Did you have any progress in your case?
I am also struggling with this one, I am not even working with these things.
I just try to connect with RDP to an Azure VM and I am getting the same message.

Let me know if you have made it, I tried to get info from the link they gave you but it's completely out of my scope.
It's just an ordinary VM I am trying to connect to :)

Thank you.

Hi @DESALERMOS Achillefs , no, it is still not resolved. I had to use another Windows machine as a jump server. You can also try to use another remote tool, such as teamviewer.
