Displaying the Assign Network Drive Dialog

Is there any way to display the Network Drive Assign dialog? It does not seem to be one of the Common Dialogs. I want to have a "Network" button on my folder select dialog, similar to the Developer Studio "Search in Files", "Select Directory" dialog. The Assign Network Drive dialog can also be displayed from the Explorer via the "Tools" menu (or the tool bar), which makes me beleave that there is an API (like SHBrowseForFolder).
