Fix A Broken Trust Relationship With Domain without Removing/Rejoining

Have you been hit with the login error: The trust relationship between this workstation and the primary domain failed.
GOOD News, there is a fix (If you can get into the machine – see below)
Just change your computer password using netdom.exe!

netdom.exe resetpwd /s: /ud: /pd:*
= a domain controller in the joined domain
= DOMAIN\User format with rights to change the computer password

Can’t log in because you don’t have the local admin password? Try this trick:

  • Turn off computer.
  • Remove network cable.
  • Turn on computer.
  • Login using regular domain credentials
  • This should work with any credentials recently used on that machine as they will be cached locally.
