Another finding is that all ASP.NET 2.0 applications on this server are working fine. The problem only occurs for .NET 4.0.

I could not identify the cause with various tools until I had to initiate a live debugging session. Let us move to Root Cause directly.

This could be because ASP.NET is not installed properly. Please try the following: Remove your website and application pool and recreate them Install ASP.NET - run this command: %windir%\Microsoft.NET\Framework64\v4.0.30319\aspnet_regiis.exe–i as an Administrator. share|improve this answer answered Nov 12 '13 at 11:03 Tom Hall 2,5201219 Thanks Tom, it worke

In fact, I completely wiped my server, reinstalled with Server 2008 R2 Standard (running on a VMWare ESXi box, not that it should matter), and cannot even get a test .aspx page to work. Here is exactly what I did: Installed 2008 R2 Standard Activated windows and enabled Remote Desktop Installed the Web Server Role with server application unavailable the necessary role services(common http, asp.net, logging, tracing, management service and FTP) Enabled the management service Installed .Net Framework 4.0 via web executable Added FTP publishing to the default web site Switched default web site application pool to asp.net 4.0 (integrated) Added a 'test.aspx' file to the inetpub\wwwroot folder (contents below) Opened a browser to http://localhost/test.aspx and received a 500.0 error (also below) What am I missing? I haven't touched IIS in a while (3+ years), so it could be something stupid/trvial. Please point it out, call me a noob; my ego can take it. Thanks, Dave test.aspx <% @Page language="C# %>
