I have a simple website (http://localhost:8889) on Windows Server 2003 and IIS6. There is nothing in this website except a page called default.htm containing a simple text string. The page is served up properly if I specify .Net 2.0 on the ASP.Net page. If I specify .Net 4.0, the browser displays a page saying the server declined to serve the page.
The same configuration was tried on a WS2003 system running in a Microsoft Virtual PC and it worked fine.
(I'm trying to deploy an MVC site that requires .Net 4.0, the question is distilled down to what I believe is the fundemantal problem.)
Can anyone help?
