I just installed Windows 10. I was part of a domain. When I try to log in I get,

"The trust relationship between this workstation and the primary domain failed."

Since I do not remember my local accounts, am I left with resetting the local administrator password with a third party tool such as the Offline Windows Password & Registry Editor and rejoining the domain or using netdom on the client.

Is there another way to make the trust relationship come back?

edit: I have tried to reset the machine account in Active Directory Users and Computers. Same error. (yes, I rebooted).

You can fix this without removing/rejoining the domain if:

A) You have a local admin account on the machine that you know the password for, or

B) You have logged in to the machine with a domain account with admin credentials in the past.

If A, just log in with the local admin credentials and then proceed to the next part. If B, disconnect the network cord, disable wireless, etc, and then log in as your local admin domain account.

Open PowerShell and run the following commands:

$credential = Get-Credential

Enter a domain admin account.

Reset-ComputerMachinePassword -Server DomainControllerName

This command will reset the machine password with the domain controller and you should be able to resume normal domain network access now.

I found this solution here and found it has worked multiple times: https://community.spiceworks.com/how_to/108912-fix-the-trust-relationship-between-this-workstation-and-the-primary-domain-failed

 

Open PowerShell and run the following commands:

$credential = Get-Credential

Enter a domain admin account.

Reset-ComputerMachinePassword -Server DomainControllerName -Credential $credential

I was not able to get my issue resolved until providing the credential as the last parameter.

As another note, I assumed my domain controller to be, well, the domain name (i.e. MyDomain.local), however for the DomainControllerName, I had to provide the Computer/Host Name of the domain controller.
