Scenario
A workstation on the domain suddenly cannot log in with domain credentials and reports a trust relationship error.
Recommended Resolution Path
- Log in with a cached local admin account.
- Test secure channel repair with PowerShell or unjoin/rejoin the device to the domain.
- Check whether the computer account was reset or duplicated in Active Directory.
- Verify time sync and DNS before rejoining the workstation.
Technician Notes
Confirm the business impact, document the root cause, and capture any preventative follow-up in the PSA or client knowledge base.
