Using Failed Request TracingTroubleshooting Failed Requests Using Tracing in IIS 7 Troubleshooting sc-win32-status 5 Failed Requests Using Tracing in IIS 7 By IIS TeamDecember 12, 2007Introduction Request-based tracing http error 401.2 - unauthorized windows server 2012 is available both in stand-alone IIS Servers and on Windows Azure Web Sites (WAWS) and provides a way to determine what exactly iis failed request tracing is happening with your requests and why, provided that you can reproduce the problem that you are experiencing. Problems like poor performance on some requests, or authentication-related failures on other requests, or the server 500 error from https://support.microsoft.com/en-us/kb/942043 ASP or ASP.NET can often be difficult to troubleshoot--unless you have captured the trace of the problem when it occurs. the following article discusses failed request tracing on IIS Server. For information about doing this with Windows Azure Web Sites click here Failed-request tracing is designed to buffer the trace events for a request and only flush them to disk if the request "fails," where you provide the definition of "failure". If you want https://www.iis.net/learn/troubleshoot/using-failed-request-tracing/troubleshooting-failed-requests-using-tracing-in-iis to know why you're getting 404.2 error messages or request start hanging, use failed-request tracing. The tasks that are illustrated in this article include: Enabling the failed-request tracing module Configuring failed-request tracing log-file semantics Defining the URL for which to keep failed request traces, including failure definitions and areas to trace Generating the failure condition and viewing the resulting trace Prerequisites Install IIS You must install IIS 7 or above before you can perform the tasks in this article. Browse to http://localhost/ to see if IIS is installed. If IIS is not installed, see Installing IIS on Windows Server 2008 for installation instructions. When installing IIS, make sure that you also install the following: ASP.NET (under World Wide Web Services - Application Development Features - ASP.NET) Tracing (under World Wide Web Services - Health and Diagnostics - Tracing) Log In as Administrator Ensure that the account that you use to log in is the administrator account or is in the Administrators group. Note: Being in the Administrators group does not grant you complete administrator user rights by default. You must run applications as Administrator, which you can do by right-clicking on the application icon and selecting Run as administrator.

Diagnosing HTTP ErrorsTroubleshooting HTTP 400 Errors in IIS Troubleshooting HTTP 400 Errors in IIS By https://www.iis.net/learn/troubleshoot/diagnosing-http-errors/troubleshooting-http-400-errors-in-iis Mike LaingNovember 27, 2012Tools Used in this Troubleshooter: Network Monitor HTTP Error logging This material is provided for informational purposes only. Microsoft makes no warranties, express or implied. Overview After sending an HTTP request to an IIS server, http://serverfault.com/questions/458394/iis-7-5-how-to-configure-custom-authentication-error-page-with-windows-authenti an HTTP client (such as Internet Explorer) may display the following type of error message: The webpage cannot be found. HTTP 400 Most likely causes: There might be a typing error in the address. If you clicked on http error a link, it may be out of date. What you can try: Retype the address. Go back to the previous page. Go to Bing and look for the information you want. If the HTTP client is Internet Explorer, and the Show Friendly HTTP Error Messages option is turned off, the error may resemble the following: Bad Request In these scenarios, IIS has rejected the client's HTTP request because the request did not meet the server's HTTP parsing http error 401.2 rules, or it exceeded time limits, or failed some other rule that IIS or HTTP.sys require incoming requests to adhere to. IIS sends the HTTP 400 - Bad Request status back to the client, and then terminates the TCP connection. Troubleshooting Methods When troubleshooting an HTTP 400 condition, it is important to remember that the underlying problem is that the client has sent a request to IIS that breaks one or more rules that HTTP.sys is enforcing. With that in mind, you will want to see exactly what the client is sending to IIS; to do this, capture a network trace of the client sending the bad request. You can analyze the trace to see the raw data that the client sends to IIS, and to see the raw response data that IIS sends back to the client. You can also use an HTTP sniffer tool called Fiddler; this is a great tool as it allows you to see the HTTP headers even if the client and server are communicating over SSL. The next data item you will want to use is the C:\Windows\System32\LogFiles\HTTPERR\httperr.log file. Beginning in IIS 6.0, the HTTP.sys component handles incoming HTTP requests before they are passed along to IIS, and is the component responsible for blocking requests that don't meet the IIS requirements. When HTTP.sys blocks the request, it will log information to its httperr.log

The site is secured by Windows authentication and that works fine: When users go to the site, they are asked for username/password and get through if authenticated. If users click Cancel or mistype password 3 times, they are shown 401 error page: Now I would like to show custom page explaining how to log-in. So I go to Error pages, select status code 401.2 and point it to the page I would like to display: Then make sure the custom errors are turned on for everybody. And kaa-boom! Authentication does not work any more, users are not presented with the password prompt. As documentation says, Windows Authentication works by sending 401 reply first, then browser asks user to provider credentials and then they work out what to do next. What happens here: on first request for the page IIS tries to send 401-header, but notices that web.config says "on 401 redirect to this page". And instead of authentication, it just gives the redirect page. I've tried replacing 401, 401.1, 401.2 - made no difference. What am I doing wrong and how to give custom page on user authentication error? p.s. Here is the web.config:
