Failed to register device (DomainName: <domain>, DeviceName: <computer_name>, AgentVersion: <version>). Directory Object in domain <domain> with sAMAccountName <computer_name> could not be found (4239510)

The error indicates that the device object has not been ingested into the backend SQL database. This typically occurs when the Directory Sync workflow has not read the device object from Active Directory. Without this step, registration cannot proceed.

• Verify Directory Sync Configuration

  • Ensure the source and target Directory Sync configurations include the Organizational Units (OUs) where the device objects reside.

• Confirm Device Location

  • Check that the device accounts exist in one of the OUs specified in the configuration.

• Validate Workflow Template Scope

  • Confirm the workflow template includes devices in its scope.

• Run Directory Sync Workflow

  • Execute the Directory Sync workflow so that device objects are read into SQL.

• Check ODM AD

  • Once the machine account is read by the workflow, it will appear in ODM AD → Devices + Servers → Not Ready.
  • At this point, the device becomes eligible for registration by the agent.
