Fixation “La relation d'approbation entre ce poste de travail et le domaine principal a échoué” erreur

Fixing “The trust relationship between this workstation and the primary domain failed” error.

Étape 1

If you know the local admin password – great! just click Switch User and log in as .\administrator and your password “.\” replaces the computer name in case you don’t know it.

If you do not know the local admin password but previously logged in with your domain credentials, you are still good. Unplug the network cable, disable wireless, then reboot the system (not necessary). After the reboot log in with your domain credentials and you should be able to get back in.

Étape 2

Open PowerShell as administrator. Run this command sequence:

$credential = Get-Credential – (enter domain admin account when prompted)

Reset-ComputerMachinePassword

Another option:

Reset-ComputerMachinePassword -Server ClosestDomainControllerNameHere
