Error Fix: Trust Relationship is Broken

Here's a quick post on fixing a broken trust situation when the local administrator username and password is a known commodity.

On Windows 7:

  1. Windows Explorer
  2. Right click My Computer/This PC --> Properties
  3. Change settings for Computer Name
  4. Change button
  5. Domain: Setting Now: DOMAIN.LOCAL
    1. Change to DOMAIN (delete .Local)
    2. Credential
  6. Reboot

That process will fix things for Windows 7 unless PowerShell is up to date then for all others including it:

  1. Log on with local admin user
  2. Reset-ComputerMachinePassword -Credential DOMAIN\DomainAdmin
  3. Log off
  4. Log on with domain user account

That's it.

If you know any other methods, especially for situations where the local admin username and password is an unknown or all local admin accounts are disabled feel free to comment or ping!

Thanks for reading. :)
