The Microsoft® Exchange Server Analyzer Tool queries the Win32_Service Microsoft Windows® Management Instrumentation (WMI) class to determine the value of the Started key for the Double-Take service. A value of True indicates that the Double-Take service is running on this Exchange Server. If the Double-Take service is detected on an Exchange Server, the Exchange Server Analyzer displays a non-default configuration message.

The Exchange Server Analyzer reports this non-default configuration for informational purposes only. No action is required.
