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 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.

How to: Display Safe Error Messages Other Versions Visual Studio 2010 .NET Framework 4 Visual Studio 2008 .NET https://msdn.microsoft.com/en-us/library/994a1482.aspx Framework 3.0 Visual Studio 2005 When your application displays error messages, it should not give away information that a malicious user might find helpful in attacking your system. For example, if your application unsuccessfully tries to log in to a database, it should not display an error message that includes the user name it is using. There are a number of ways to control error messages, including the following: Configure the application not to show verbose error messages to remote users. (Remote users are those who request pages while not working on the Web server computer.) You can optionally redirect errors to an application page. Include error handling whenever practical and construct your own error messages. In your error handler, you can test to see whether the user is local and react accordingly. Create a global error handler at the page or application level that catches all unhandled exceptions and routes them to a generic error page. That way, even if you did not anticipate a problem, at least use
ASP.NET web-site, and would like the ability to conditionally show/hide runtime error messages depending on who the user visiting the site http://weblogs.asp.net/scottgu/Tip_2F00_Trick_3A00_-Show-Detailed-Error-Messages-to-Developers is.For a normal user visiting the site you want to be able to display a friendly error message like this when a runtime error occurs: But when someone http://serverfault.com/questions/670853/iis-8-show-classic-asp-errors-in-browser within the “developers” security role of your application remotely accesses the site you want to instead show a more detailed exception stack trace error message about the error message problem without having to change any configuration data: The below post describes how to use ASP.NET’s role-based security architecture in conjunction with the Global.asax Application_Error event handlerto enable this. You can also download a sample I’ve built that shows how to implement this here.Some Background Discussion on Error Handling and ASP.NET Custom Error Pages:ASP.NET and display error message .NET support a rich error-handling architecture that provides a flexible way to catch/handle errors at multiple levels within an application. Specifically, you can catch and handle a runtime exception with a class, within a page, or on the global application level using the Application_Error event handler within the Global.asax class. If a runtime exception isn’t handled/cancelled by one of these mechanisms, then ASP.NET’s Custom Error Page feature will kick-in, and an error page will be sent back to the browser accessing the application.ASP.NET’s Custom Error Page feature can be used to configure a “friendly error page” to be displayed to end-users in place of the standard “server error occurred” message sent back by ASP.NET. For example, the below web.config file section will cause remote users visiting the site to be redirected to a “friendlyErrorPage.htm” file anytime a runtime error occurs (note: HTTP 500 status code responses indicate runtime errors on the server):

(I have turned off "Show Friendly Http Messages". In IIS 8 I have gone to ASP settings and set "Send Errors to Browser = True". I've got simple ASP pages working fine. I'm porting code from Windows 2003 over to 2012. And having to debug misc issues. The only place I see the error is in the IIS Log after a few minutes. That's way to slow to fix the errors, and it doesn't give much info. I'm running the browser on the remote server itself. Ideally want to get errors in any browser, not just IE. Added 02/25/2015 - it seems to work maybe 5% of the time.
