Looking at the response with Fiddler yields: HTTP/1.1 500 500 internal server error iis 8 Internal Server Error Server: Microsoft-IIS/7.5 X-Powered-By: ASP.NET Date: Mon, 05 Mar 2012 15:59:52 GMT Content-Length: 0 There's not much to work with here! I checked the event log, there was https://blogs.iis.net/rickbarber/working-past-500-internal-server-error nothing there. So I started looking around for an error log of some sort (I used to play with Apache back in the days) turns out there's no such thing in IIS. Some googling led me to an in-depth article:Troubleshoot IIS7 errors like a pro. I enabled detailed error messages for my website, still no luck. Finally, I figured http://www.dotnetnoob.com/2012/03/iis-500-errors-leave-clues-in-log.html out that the easiest way to get an indication of what's going on is to check the IIS log. In the default setup, IIS keeps the logs for each website in:C:\inetpub\logs\LogFiles. Here's a log entry from my logfile (shortened for readability): 2012-03-05 15:59:52 ::1 GET /Somesite/ - 443 - ::1 Mozilla/5.0 500 22 50 1 Notice the "500 22" in the log? That's the 500 error, along with its substatus. The substatus is the key here, as you can look that up inMicrosoft's document onThe HTTP status codes in IIS 7.0 and in IIS 7.5. Voila, my error was actually: 500.22 - An ASP.NET httpModules configuration does not apply in Managed Pipeline mode. I can work with that. Of course, you could also enable failed request tracing in IIS if you're a pro, here's a walkthrough by the IIS team:Troubleshooting Failed Requests Using Tracing in IIS 7. I tried it, and it also revealed the substatus of the response. Still, checking the IIS log was a much faster way of getting an indication of what the

request to it. This seems to be a popular theme on IIS.NET forums these days, and after answering a hundred or so of these posts, I figured I should do something to help people track down and fix their issues with a little less frustration. Update: We recently launched a service that significantly helps you understand, troubleshoot, and improve IIS and ASP.NET web applications. If you regularly troubleshoot IIS errors, manage Windows Servers, or tune ASP.NET performance, definitely check out the demo at www.leansentry.com. Server software, and web servers specifically, are very complex and highly configurable systems that support multi-tier applications using a variety of technologies and subsystems, and endure further complexity due to security, performance, and reliability demands, so it’s a wonder it all works as well as it does in the end. IIS7 strives to improve the experience of diagnosing and solving problems when they do occur, so knowing how to use the new IIS7 diagnostics features can come a long way in helping you become a pro at troubleshooting server problems. First things first - what’s the problem? I often find myself asking this question on the forums when someone posts something like “Help, I moved to IIS7 and now my application doesn’t work!”. Huh, what doesnt work? When your site stops working, the first thing you need to do is determine what the error actually is before we can move any further. IIS7 has much better error messages that will often tell you exactly what the problem is, and help you fix it. Unfortunately, sometimes getting to this error is the main challenge. Let’s look at a few things you may need to do to get there: 1) Disable IE “Friendly HTTP error messages” IE will by default replace the actual error messages coming from the server with a “friendly” error message, which hides the error contents we need to see. For example, for a 404 Not Found error, you may instead see the following: To disable this and see the real error coming from the server, you need to go to “Tools > Internet Options”, choose the Advanced tab, and clea
