Can IE7 on the INTRAnet open the actual network document in ms word or ms excel

streaming the file wont work because it will create a local copy in the users temp folder.

opening within IE wont allow editing of the actual file, it prompts the user to save as.

i have the page allowing uploading and linking, creating an organized list of documents using the UNC path for linked documents, and webserver path for attached documents. This is a .net 2.0 c# intranet.

we are on the INTRAnet, and i should be allowed to leverage this functionality. i understand the restriction for Internet sites. Ive tried the vbscripts and jscripts in the .dot examples found on searching, but i get the "ie can't create the ActiveX object" error
