How to Fix Trust Relationship between this Workstation and the Primary Domain failed

Last Updated on August 7, 2025 by Arnav Sharma

This error means the secure connection between your computer and the Active Directory domain has broken. Causes include:

• Password Mismatch: Computer and domain controller have different stored passwords for the computer account.

• Network Issues: Connectivity problems preventing communication with the domain controller.

• Time Synchronization: Large time differences between computer and domain controller.

• DNS Problems: Issues resolving the domain controller’s address.

• Deleted or Corrupt Computer Account: The computer’s account in Active Directory may be missing or damaged.

Troubleshooting Steps:

1. Basic Checks

• Internet Connectivity: Ensure the computer has network access and can reach the domain controller. Use ping to test connectivity to the domain controller by its name and IP address.

• Time Synchronization: Make sure computer time is in sync with the domain controller. Incorrect time can disrupt authentication.

• DNS Settings: Verify that your computer’s DNS settings are correctly configured to use the domain’s DNS servers.

2. Reset the Computer Account

This is often the fastest fix:

• Using Command Line (Netdom):
  • Log in as local administrator.
  • Run a command prompt as administrator.
  • Type: netdom resetpwd /server:SERVER_NAME /userd:DOMAIN_NAMEADMIN_USER /passwordd:ADMIN_PASSWORD
    • Replace placeholders with your domain information.

• Using Active Directory Users and Computers:
  • Log into a domain controller as domain administrator.
  • Open “Active Directory Users and Computers”.Locate the computer account in question.
  • Right-click the computer account and select “Reset Account”.

4. Advanced: Manually Repairing Trust Relationship (if above methods fail)

• Verify Computer Account in Active Directory: Ensure the computer’s account still exists in AD. If missing, create it manually.

• Utilize “Test-ComputerSecureChannel” in PowerShell: Requires some expertise. Check Microsoft documentation for instructions.

Additional Notes:

• Permissions: Domain administrator rights might be needed for some steps.

• Multiple Workstations: If many are affected, consider broader domain controller or network problems.
• Backups: Have backups before major AD changes.
