User got this message "The trust relationship between this workstation and the primary domain failed"

Seema Kanwal Gurmani 341

Dear Community,

Kindly note that a user in my domain got this error. After he restarted the machine, the error disappeared.

The user's machine is domain joined.

But it is the second time that he got the error in last few months. Why did this user got the error & how can I avoid this in the future?

Answer 1

The message indicates a temporary failure of the secure channel between the user’s domain-joined computer and a domain controller. This happens when the computer account’s secret (machine password) on the client and in Active Directory are out of sync or the secure channel can’t be validated at that moment.

Typical causes include:

The machine’s password in Active Directory is newer or older than the local one (for example, due to replication delays, DC restore, or network issues).
Transient connectivity or domain controller issues that prevent the workstation from authenticating to a DC.

A restart can temporarily “fix” it if the issue was transient (for example, the machine reconnects to a healthy DC, or the secure channel is re-established). However, repeated occurrences suggest an underlying secure channel or machine-password synchronization problem.

To reduce or avoid recurrence:

Verify and repair the secure channel when the issue occurs:
- Sign in with a local administrator account.
- Run netdom verify ComputerName /domain:YourDomainName to test the secure channel.
- If problems are found, reset the machine password and secure channel:
```
     netdom resetpwd /server:DomainControllerName /userd:Domain\Username /passwordd:*
     netdom reset /domain:YourDomainName /userd:DomainUsername /passwordd:*
```
- Restart the device.
If secure channel issues persist, investigate root cause:
- Collect data and logs as described in the secure channel troubleshooting guidance, then determine whether the client or Active Directory holds the newer machine password and follow the corresponding remediation.
As a last resort, remove and rejoin the computer to the domain if the computer account is corrupt or repeatedly loses trust.
Ensure the computer name is consistent in the registry keys used by the OS for hostname and computer name, as mismatches can contribute to trust issues.

If this user’s machine is the only one affected and the error is infrequent, monitor it and, at the next occurrence, run the secure-channel tests and resets above to confirm whether the machine password or DC side is at fault.
