Iis 500 Internal Server Error Log
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
Iis 500 19
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 50 1 Notice the "500 22" in the log? That's the 500 500.19 - configuration data is invalid. 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.

In my experience, if the event log is empty than the request wasn't correctly routed to the worker process. In one of our recent deployments we saw the app work intermittently with about 50% of the requests randomly failing with the 500 error and nothing in the logs. I suspect something is going wrong with the AppDomain unload that occurs after deployment. Out of curiosity, are you running antivirus in your production environment? Does an IIS reset solve the issue (until the next deployment)? –ShadowChaser Feb 21 '13 at 16:17 add a comment| 4 Answers 4 active oldest votes up vote 23 down vote accepted Take a look at IIS7's Failed Request Tracing feature: Troubleshooting Failed Requests Using Tracing in IIS 7 Troubleshoot with Failed Request Tracing The other thing I would do is tweak your
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 https://blogs.iis.net/rickbarber/working-past-500-internal-server-error when it knows something has gone wrong but it is unable to be more specific http://www.dondraper.com/2011/01/500-internal-server-error-from-iis-7-5-on-windows-2008-r2/ 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 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 internal server IIS 7 or IIS 8, just about any error that you get from 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 internal server error site from a browser located on the same server. You may need to turn off ‘show friendly http errors.’ Temporarily add the following within the appropriate tags in your web.config file:
2011 by Don Draper 23 Comments Tweet You are running an ASP or ASP.NET web application on IIS on Windows 2008 R2 from a remote web browser and you constantly see following error message. While this is the proper results for a production server (you never want to show remote users the details of an error), it is not helpful while testing a new installation…as a developer you need to see the error messages on the remote browser. There is an obscure setting that controls this for both ASP and ASP.NET. I hope the following will help anyone needing to see error details on a remote connected browser. For Classic ASP Errors In IIS Manager, select your ASP site, the double-click the ASP icon in the IIS section. The configuration settings for this ASP applications will appear. Open the section for Debugging and make sure the option Send Errors to Browser is set to True. Review other settings while you are here to ensure they match want you want. For Classic ASP and ASP.NET Errors Just making the change above seems to work find under IIS on Windows 7 but not Windows 2008 R2. You may need to change one other setting. In IIS Manager, select the ASP or ASP.NET site, the double-click the Error Pages icon in the IIS section (do not confuse with the .NET Error Pages in the ASP.NET section) . The list of error codes and related IIS Error Pages will appear. Select the one for 500 errors and right-mouse, then choose Edit Feature Settings from the popup menu. The default settings is the third option which only allows detailed errors to be sent to a browser on the same server. Change this setting to the second option labeled Detail errors and then details of your code or script errors will be sent to the browser even if it is a remote quest. If you are using Internet Explorer, also make sure that Show Friendly Errors is not enabled. This is not a problem for Firefox users. Be sure and change this setting back to the default if and when the server is used in a production environment. When that is the case, use the NT Event log for ASP errors (also set in the ASP settings section) and .NET Error Tracing as better ways to view the details of production errors. Hope this helps! Now you can view ASP and ASP.NET errors in the browser remotely. Here is an example of a Classic ASP error.
