Windows 10: I need to know how best to move a set of workstations from a failed on-premise domain to...

I have a small client with an on-premise domain. The domain controller has failed and there is no backup. Their workstations are domain joined. They all have Microsoft 365 business premium licenses. The Azure AD Domain is not synced or even aware of the on-premise domain. What is the least disruptive way to move the user workstation to Azure AD management without losing any of their personal files. I moved one of them by creating a local administrator account and then unjoining the workstation from the domain. Logged in as the local user. connected that user to the Azure AD. As it conn

the trust relationship between this workstation and the domain failed

I am trying to map to a share on a VMware virtual server and I keep getting
the trust relationship between this workstation and the domain failed error message. I have tried every conceivable suggestion on the web to resolve this issue including adding removing the computer from the domain, deleting the computer record in
AD, using credential manager and PowerShell to fix the issue. There are several other machines on the network experiencing the same issue. I've rebooted the VMware hosts the servers and even our switches and nothing works. I can't do a system restore because
all the options are greyed out in that panel. We are also seeing this issue when a programs/script running on one of our windows servers tries to connect to another of our windows servers. Any suggestions?

 

UnattendedJoin error: failed to find the domain data (0x6e)

Thanks for the suggestion! I don't want to add a domain account, as this is a generic unattended install that will be used for all company machines. Do you think it's possible that the computer would join the domain if, instead of using UnattendedJoin in specialize, I used your steps but left out the specific account?

The other thing I was thinking was to use a generic account to allow the domain join during the specialize step. I added a machine password in the UnattendedJoin component, and instead of getting the error listed above, I got an authentication error, which makes me think I could probably do a secure join instead of the unsecure join.

Thoughts?

 

Trust relationship between this workstation and the primary domain failed

I want to know the root cause for trust relationship error so please let me know which logs to check to find out exact reason for workstation-domain trust relationship error.

I want to identify issue using the logs available in workstation machine.
