However; there is nothing showing up in the Application Event Log where I would expect to see a (more) detailed description of the entry. How can I go about diagnosing this issue? iis-7.5 windows-event-log 500-error asp.net-mvc share|improve this question edited Jul 16 '12 at 7:55 asked Jul 15 '12 at 21:25 Greg B 4893825 I've had the exact same issue here. 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 Tak

HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfil up vote 2 down vote favorite I have a MVC3 web site, which works well on internal server IIS Express, but after publishing to IIS 7.5 I got that weird error. The full error message is: HTTP Error 500 (Internal Server Error): An unexpected condition was encountered while the server was attempting to fulfill the request. I published using 'File system' method, for web site I created a separate site in IIS, separate application pool with .NET 4.0 and Integrated mode.

This is the default error page Chrome displays when it receives a 500 HTTP response from the server with no content. You need to find the cause of this error. Open the Event Viewer (Win+R, type "eventvwr.msc", click OK). Expand "Windows Logs" and click "Application". Look for an error or warning that relates to IIS, W3SVC or similar. It's likely an error that's occurring before the request reaches the .NET pipeline. share|improve this answer answered Jun 28 '13 at 9:28 greg84 5,32611836 1 Thanks. I found an error "Forms authentication failed for the request. Reason: The ticket supplied was invalid." Never seen such kind of error, further investigation is needed. –berliner Jun 30 '13 at 16:03 add a comment| Your Answer draft saved draft discarded Sign up or log in Sign up using Google Sign up using Facebook Sign up using Email and Password Post as a guest Name Email Post as a guest Name Email discard By posting your answer, you agree to the privacy policy and terms of service.

IIS 500 errors leave clues in the log Email ThisBlogThis!Share to TwitterShare to FacebookShare to Pinterest Yesterday I was playing around with thevalidateIntegratedModeConfiguration="true" setting on IIS 7.5. To my surprise I got an empty response back, with no indication of what went wrong. Looking at the response with Fiddler yields: HTTP/1.1 500 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 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 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 problem was, and sometimes that's all you need. So check your logs first, then start troubleshooting like a pro! Posted by André N.
