Issue Title: Cannot RDP into a domain-joined VM with domain credentials
Created a new Azure Active Directory Domain Services (AADDS) in its own subnet. In doing so, added myself as a member of the AAD DC Administrators group, then set up new password for authentication to the AADDS. Password hash sync is enabled from Azure AD to Azure ADDS.
Then created a VM of Windows Server 2019 in its own dedicated subnet, set up RDP as the connection method for the VM, then logged into to the VM with RDP using VM's own local account (= local admin account)
Then joined the VM to the Azure Active Directory Domain Services, restarted the VM
Issue details: -
I can RDP into the domain-joined VM using local admin account, but not the domain credentialsIt is at the this point, that the main issue is there<<
The domain credentials were entered in the UPN format, gave the error, also tried with SAMaccount format, gave the same error.
In the Windows Security prompt of the RDP, after entering the domain credentials, I see the error: "Your Credentials did not work. The credentials that were used to connect to the <Public IP Address of the VM> did not work. Please enter new credentials"
Troubleshooting: -
-VM RDP connection security rules are fine: Port # 3389 is open
-Un-joined the VM to the domain, re-joined the VM, reboot the VM, still main issue persists
-Inside the VM, went into secpol.msc from start menu then made sure that administrators and remote desktop users are part of the the rule: "allow users to logon to Remote Desktop" and that no users/groups exist in the rule: "deny users logon to Remote Desktop"
-Re-deployed the VM under a different Windows image (Windows 10 pro), still same issue
Help is welcome
Thank you
