Iis 6 Error 500
41 IIS 7.5 , 2008rc2, classic asp, 500 error msg: The page cannot be displayed because an internal server error has occurred. I need to know how to configure IIS to get a more detailed error.

So if "Send Errors To Browser" is not working set also this: Error Pages -> 500 -> Edit Feature Settings -> "Detailed Errors" Also note that if the content of the error page sent back is quite short and you're using IE, IE will happily ignore the useful content sent back by the server and show you its own generic error page instead. You can turn this off in IE's options, or use a different browser. share|improve this answer edited Jan 21 '14 at 15:03 answered May 4 '10 at 13:43 Vaclav Elias 2,48621122 8 Error Pages -> 500 -> Edit Feature Settings -> "Detailed Error" Thanks!!!!! –Pablo Martinez May 11 '12 at 12:55 6 If it's still not working, disable friendly http error messages –Tim Partridge Feb 22 '13 at 18:53 If "Error P

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 22 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
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 http://www.dotnetnoob.com/2012/03/iis-500-errors-leave-clues-in-log.html 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 http://www.dondraper.com/2011/01/500-internal-server-error-from-iis-7-5-on-windows-2008-r2/ 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 error 500 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 iis error 500 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. Klingsheim at Tuesday, March 06, 2012 Labels: ASP.NET, IIS 7.5, Ninja tricks, server 2008 4 comments:
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 setti
