Cause: When Discovery is scheduled for the Windows devices, It checks all the credentials for Windows in our instance for the device we are trying to discover. After Powershell tries all the credentials in the instance and it fails to logon with any of them. Next by default, It attempts to logon by using MID Server service credentials.

Solution: Add a configuration parameter to the MID Server.

Mid.powershell.local_mid_service_credential_fallback = false

Note: After changing the parameter, please make sure to restart the MID Server.

Test Results:

1. Run the discovery again for the device failing with this error.
2. Open the “Input” XML file for WMI in ECC Queue.
