Dom Config failure server 2008 r2

anyone know how to fix the following error?

Retrieving the COM class factory for component with CLSID {0002DF01-0000-0000-C000-000000000046} failed due to the following error: 80070005 Access is denied. (Excep开发者_如何学Gotion from HRESULT: 0x80070005 (E_ACCESSDENIED)).

In the application im trying to get it to open a page and input data at a certain url using SHDocVw.InternetExplorer

This should solve it:

Add this <identity impersonate="true" userName="Domain\MyUsername" password="MyPassword"/> in web.config after <authentication mode="Windows" />
