Re-join a computer to the domain

Posted on by

When a computer loses its domain membership you can now use powershell to reset computer connection.

Log in with a local account to the computer getting the error message, from a powershell command use this command to check the status of the computer’s domain membership.

Test-ComputerSecureChannel -Credential (Get-Credential) -Verbose

Add the -Repair parameter to reset the secure channel, you’ll need domain creds that have permission to join a computer to the domain.

UPDATE: Since I posted this article I found another powershell command that will reset the computer password when you know its out of sync.

PS C:\> Reset-ComputerMachinePassword -Server "DC01" -Credential Domain01\Admin01
