what went wrong. Looking at the response with Fiddler yields: HTTP/1.1 500 Internal Server Error iis logs 500 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 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 500.19 - configuration data is invalid. 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 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 22 500 0 64 iis error 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 problem was, and sometimes that's all you need. So check your logs first, then start troubleshooting like a pro! Posted by André N.

and provides a way to determine what exactly is happening with your requests and why it is happening, provided that you can reproduce the problem that you are experiencing. Problems like poor performance on some http://www.dotnetnoob.com/2012/03/iis-500-errors-leave-clues-in-log.html requests, or authentication-related failures on other requests, or the server 500 error from ASP or ASP.NET can often be difficult to troubleshoot--unless you have captured the trace of the problem when it occurs. the following article discusses failed request tracing on IIS Server. For information about doing this with Windows Azure Web Sites , click here. Failed-request tracing is designed to buffer the trace events for a request and https://www.iis.net/learn/troubleshoot/using-failed-request-tracing/troubleshooting-failed-requests-using-tracing-in-iis-85 only flush them to disk if the request "fails," where you provide the definition of "failure". If you want to know why your requests are returning a specific HTTP status code, e.g., 401 or 404, or if a request is taking a while to process or is not responding, then you can use failed request tracing. The tasks that are illustrated in this article include: Enabling the failed-request tracing module Configuring failed-request tracing log-file semantics Defining the URL for which to keep failed request traces, including failure definitions and areas to trace Generating the failure condition and viewing the resulting trace Prerequisites Install IIS You must install IIS 8.5 before you can perform the tasks in this article. Browse to http://localhost/ and verify that the Internet Information Services splash screen is displayed. If IIS is not installed, see Installing IIS 8.5 on Windows Server 2012 R2 for installation instructions. When installing IIS, make sure that you also install the following: ASP.NET 3.5 (under Web Server (IIS)/Web Server/Application Development Features/ASP.NET 3.5) ASP.NET 4.5 (under Web Server (IIS)/Web Server/Application Development Features/ASP.NET 4.5) Tracing (under Web Server (IIS)/Web Server/Health and Diagnostics - Tracing) Log In as Administrator Ensure that the account that you use to log in is the administra
you deploy it to your IIS server. Now you’re getting the dreaded 500 – Internal server error. What are you to do? As you may know, a HTTP 500 error is a generic error message returned by a web server when it knows something has gone wrong https://blogs.iis.net/rickbarber/working-past-500-internal-server-error but it is unable to be more specific about the error. That’s not necessarily helpful, though, when you are trying to figure out what is causing the error so you can fix it and get your web site to load. Here http://windowsitpro.com/web-development/iis-troubleshooting-tips-and-tricks are a few tips to help you find the real error so you can get your site loading properly. Classic ASP If you are running Classic ASP on IIS 7 or IIS 8, just about any error that you get from internal server an out-of-the-box installation will be a 500 error. You should check out this blog post for more information on developing Classic ASP applications in IIS 7 or later. Tips for finding the real error Run the site directly on the server – depending on the configuration of your site/server, you may be able to see the real error if you load the site from a browser located on the same server. You may need to turn off ‘show friendly http errors.’ Temporarily internal server error add the following within the appropriate tags in your web.config file:

IIS can do almost anything, from servicing simple static pages to being a fully blown, enterprise-grade reverse proxy server. Like any complex product, though, IIS requires troubleshooting on occasion. Here we'll look at some of the most common challenges that web developers and administrators face when deploying and developing applications for IIS and how to troubleshoot them properly. Runtime Errors and Exceptions The most common issues customers encounter when deploying or developing for IIS are runtime errors and exceptions, which include various errors from the 40x and 50x families of HTTP errors. These errors include the common 404 and less-common 400 errors, as well as the dreaded 500 internal server error. The appearance of these errors varies depending on the IIS server's configuration. The HTTP 500 error, which is typically an application or pipeline error where something failed before the application sent any response, could manifest itself as a simple error in the browser, such as the examples shown in Figure 1. However, if the error occurs in a managed code .NET application, the error might look like that shown in Figure 2. The first step in figuring out such errors is a differential diagnosis. This means that we need to deduce from user reports that the site hangs are actu
