The Microsoft® Exchange Server Analyzer Tool reads the following registry entry to determine the value data for the ObjectName value:


The ObjectName value in this registry branch indicates the service account settings for the Microsoft Windows® Management Instrumentation (WMI) service, known as the Winmgmt service. If the Exchange Server Analyzer finds the value data for ObjectName is not equal to LocalSystem, the Exchange Server Analyzer displays an error.

This error indicates that the WMI service is not running in a supported configuration. If you run the WMI service under any account other than the LocalSystem account, you can cause permission errors and access errors.

To resolve this error, you must configure the WMI service to start under the LocalSystem (SYSTEM) account.

To configure the WMI service account

  1. Open the Services Microsoft Management Console (MMC) snap-in.

  2. Locate and stop the Windows Management Instrumentation service.

  3. Double-click Windows Management Instrumentation service.

  4. On the Log On tab of the Windows Management Instrumentation Properties page, select Local System account under Log on as, and then click Apply.

  5. Under Service status, click Start, and then click OK.

  6. Close the Services snap-in.
