You receive the error, "Unable to determine LAPS password".
This error is most likely caused by the target computer not being configured with the LAPS local admin or other LAPS configuration issues for that particular target.
Test the target computer’s LAPS account outside of PDQ to determine the cause of the LAPS failure and configure the target computer with the appropriate LAPS user and/or configuration.
For additional troubleshooting, please see the LAPS_OperationsGuide.docx that comes with Microsoft’s LAPS download here:
