Some machines not Hybrid Azure AD Joining despite correct settings
Some machines not Hybrid Azure AD Joining despite correct settings.
The task for dsregcmd returns 0x1 but does not join a machine. When trying to run the command manually, I get a "Run as system". This is on 1803.
We have several 1809 machines that throw an HTTPS 400 error code. We successfully are able to connect to the websites listed on the setup process.

Contact Microsoft Azure AD team, they have a tool which will remove any remnants of registrations. Afterwards, execute an AAD connect sync cycle and afterwards make sure the user will logon to the sytem with a line of sight to the domain controller and to the internet (and that the users logs on with an account that is synced to Azure AD).
You can package the tool and distribute it to all your users as available through SCCM so your Servicedesk has easy access to the tool.
I'd like to see that Microsoft integrates the tool into Windows 10.
