ASPX pages all showing page not found (even though they exist), New IIS 8 install Server 2012 When I check the IIS manager it appears the aspx handler is missing, I see an option to add it, but have not idea what to put in, or if that's even the right way to enable loading of ASPX pages. .NET 4.5 is enabled, and html pages load fine. Any ideas how to get the server to parse aspx pages, rather than displaying the 404? TIA
