- Internal Server Error The page cannot be displayed because an internal server error has occurred. 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 Take a look at IIS7's Failed Request Tracing f

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, http://serverfault.com/questions/407954/how-to-diagnose-a-500-internal-server-error-on-iis-7-5-when-nothing-is-written-t 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 http://www.dondraper.com/2011/01/500-internal-server-error-from-iis-7-5-on-windows-2008-r2/ 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. Share and Enjoy:PrintFacebookTwitterLinkedInDiggd

Running Classic ASP Applications on IIS 7 and IIS 8Classic ASP https://www.iis.net/learn/application-frameworks/running-classic-asp-applications-on-iis-7-and-iis-8/classic-asp-script-error-messages-no-longer-shown-in-web-browser-by-default Script Error Messages No Longer Shown in Web Browser by Default Classic ASP Script Error Messages No Longer Shown in Web Browser by Default By Robert McMurrayFebruary 19, 2009In earlier versions of IIS, error messages from https://bobmckay.com/web/classic-asp-custom-errors-iis7iis7-5/ classic ASP scripts were sent to a Web browser, by default. Because these error messages might reveal sensitive information to malicious users, IIS 7 and above disables this feature by default. When your classic ASP scripts encounter internal server an error in IIS, you receive the following error message by default: An error occurred on the server when processing the URL. Please contact the system administrator. If you are the system administrator please click here to find out more about this error. You can customize the ASP script error message, and also determine whether to return the script errors to a Web browser. Note: As a best practice for security, you should only internal server error enable sending ASP script error messages to a Web browser on a development or test computer; returning script error messages to a Web browser can unintentionally expose more information than you intended to show. Working with User Access Control You need to make sure that you follow the steps in this document by using an account that has full administrative permissions. This is best accomplished by using one of two methods: Log in to your computer by using the local administrator account. If you are logged in using an account with administrative permissions but that is not the local administrator account, open all applications and all command prompt sessions by using the "Run as Administrator" option. These above conditions are required because the User Account Control (UAC) security component in Windows Vista and Windows Server 2008 will prevent administrative access to the IIS configuration settings. For more information about UAC, see the following documentation: User Account Control Customizing Classic ASP Error Messages The configuration settings that you use to customize these settings are in the following list: scriptErrorMessage This is an optional string attribute that specifies the error message that will be sent to the browser when specific debugging errors are not sent to the client. scriptErrorSentToBrowser This is an optional Boolean attribute that specifies whether the writing of
/ Classic ASP Custom Errors on IIS7/IIS7.5Posts navigation Classic ASP Custom Errors on IIS7/IIS7.5UPDATE: If you are also looking for a Classic ASP Error Handling Script, I have pasted my basic one here and if you're working with ASP components, you might find my Classic ASP Component Detection Script useful.We recently migrated eighty websites from a Windows Server Standard 2003 (IIS6) to Windows Server Standard 2008 R2 (IIS7.5).Most of the websites use custom error pages to capture errors and send the error back to us.Since moving to Server 2K8 R2, all of our custom error scripts started reporting no useful information (for example, Linenumber: 0).If you are responsible for an IIS installation, I strongly recommend having a copy of the IIS Administrator's Pocket Consultant around - great for those emergencies!Attempt 1: Web.ConfigFirstly I tried using web.config in my websites root to set the custom error page, this actually worked in so far as the page was called when errors occurred and the website visitors were shown a custom page but none of the error details (error code, line number, error description, etc) are available.All examples I found online of a web.config showed just a few lines (very frustrating for beginners) so here is my full web.config:
