Managing Services and Network Settings by Using WMI Provider
The WMI provider is a published interface that is used by Microsoft Management Console (MMC) to manage the Microsoft SQL Server services, and network protocols. In SMO, the ManagedComputer object represents the WMI Provider.
The ManagedComputer object operates independently of the connection established with the Server object to an instance of SQL Server, and uses Microsoft Windows credentials to connect to the WMI service.
