The method “Start” of the BizTalk Server WMI provider class “MSBTS_HostInstance”

I am still wondering why I get this error message when I try to start an orchestration using Visual Studio. In your BT explorer when you right click on an orchestration and select start from pop-up menu, you will get BisTalk Express – Start dialog box where all the check boxes are selected by default.

Unable to update BizTalk Host:
Failed to execute method “Start”.
The method “Start” of the BizTalk Server WMI provider class “MSBTS_HostInstance” cannot be executed because of a failure to retrieve the class.
Not Supported.

I suspect Windows WMI engine not able to execute the scripts which are made available in the BizTalk folders C:\Program Files\Microsoft BizTalk Server 2004\SDK\Samples\Admin\WMI\

But you can start your orchestration if you unselect the BizTalk Host check box, in the get BizTalk Express – Start dialog box. This will not restart your host, but you can restart the Host later.

And you can restart your BizTalk Host by using Service Window.


If any one knows it better, pls. let me know why this problem occurs.
