My web application is built in VS 2012, using .NET 2.0 (due to deployment on a Windows Server 2003 box and company standards). I have some links to MS Word and Excel documents on our application's home page. If the links are to .doc and .xls files (Office 97-2003 format), the files open normally. If I modify the links to open .xlsx or .docx files, they open normally when debugging locally, but when the solution is deployed to our server I get a "page not found" error. The files being linked to are present and there are no typos. Is this a .NET issue? Is it something else? The application runs on our company's intranet.
