Problems like poor performance on some requests, or authentication-related failures on other requests, or the server 500 error from ASP or ASP.NET can often be difficult to troubleshoot--unless you have captured the trace of the problem when it occurs. </p> <p class="tree-view-adjacent">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 to know why you're getting 404.2 error messages or request start hanging, use failed-request tracing. </p> <p class="tree-view-adjacent">The tasks that are illustrated in this article include: </p> <ul class="tree-view-adjacent"> <li class="tree-view-adjacent">Enabling the failed-request tracing module </li> <li class="tree-view-adjacent">Configuring failed-request tracing log-file semantics </li> <li class="tree-view-adjacent">Defining the URL for which to keep failed request traces, including failure definitions and areas to trace </li> <li class="tree-view-adjacent">Generating the failure condition and viewing the resulting trace </li></ul> <h2 class="tree-view-adjacent">Prerequisites </h2> <h3 class="tree-view-adjacent">Install IIS </h3> <p class="tree-view-adjacent">You must install IIS 7 or above before you can perform the tasks in this article.

You already configured IIS to capture trace logs for <a href="https://web.archive.org/web/20130320194905/http://localhost/*.asp">http://localhost/*.asp</a> requests that fail with an HTTP response code of 404.2. Now verify that it works. </p> <h3>Step 1 : Generate an Error and the Failure Request Log File </h3> <ol> <li>Open a new Internet Explorer window. </li> <li>Type in the following address: <a href="https://web.archive.org/web/20130320194905/http://localhost/test.asp">http://localhost/test.asp</a>. </li> <li>You should see the following: </li></ol> <p><a href="https://web.archive.org/web/20130320194905/http://i3.iis.net/media/7191819/troubleshooting-failed-requests-using-tracing-in-iis-266-file11.png?cdn_id=2013-03-12-001"><img border="0" alt="" src="https://web.archive.org/web/20130320194905im_/http://i3.iis.net/media/7191819/troubleshooting-failed-requests-using-tracing-in-iis-266-file11.png?cdn_id=2013-03-12-001"></a> </p> <h3>Step 2 : View the Failure Request Log File </h3> <ol> <li>Now that you have generated a failed request, open a command prompt with administrator user rights and navigate to %systemdrive%\inetpub\logs\FailedReqLogFiles\W3SVC1. </li> <li>Run <strong>start</strong> to start an Internet Explorer window from the directory. </li></ol> <p><a href="https://web.archive.org/web/20130320194905/http://i1.iis.net/media/7191813/troubleshooting-failed-requests-using-tracing-in-iis-266-file12.jpg?cdn_id=2013-03-12-001"><img border="0" alt="" src="https://web.archive.org/web/20130320194905im_/http://i1.iis.net/media/7191813/troubleshooting-failed-requests-using-tracing-in-iis-266-file12.jpg?cdn_id=2013-03-12-001"></a> </p> <p mce_keep="true"> </p> <p>3. Notice a few things here: When IIS writes the failed request log file, it writes one file <em>per failed request</em>. A <em>freb.xsl</em> style sheet is also written, one per directory. This helps when you view the resulting failure request log files (such as <em>fr000001.xml</em> above). </p> <p>4. Right-click the log file for the 404.2 error, and click <strong>Open With -> Internet Explorer</strong>. If this is the first time that you are opening a Failed Request Tracing file, you must add <strong>about:internet</strong> to the list of trusted sites, since Internet Explorer's Enhanced Security Configuration is enabled by default. If this is the case, you will see the following: </p> <p><a href="https://web.archive.org/web/20130320194905/http://i3.iis.net/media/7191807/troubleshooting-failed-requests-using-tracing-in-iis-266-file13.png?cdn_id=2013-03-12-001"><img border="0" alt="" src="https://web.archive.org/web/20130320194905im_/http://i3.iis.net/media/7191807/troubleshooting-failed-requests-using-tracing-in-iis-266-file13.png?cdn_id=2013-03-12-001"></a> </p> <p>5. In the <strong>Internet Explorer</strong> dialog box, click <strong><span>A</span>dd…</strong> to add <strong>about:internet</strong> to the list of trusted sites. This allows the XSL to work. You will see the following after adding <strong>about:internet</strong> to the list of trusted sites:</p> <p><a href="https://web.archive.org/web/20130320194905/http://i3.iis.net/media/7191801/troubleshooting-failed-requests-using-tracing-in-iis-266-file14.png?cdn_id=2013-03-12-001"><img border="0" alt="" src="https://web.archive.org/web/20130320194905im_/http://i3.iis.net/media/7191801/troubleshooting-failed-requests-using-tracing-in-iis-266-file14.png?cdn_id=2013-03-12-001"></a> </p> <p>A summary of the failed request is logged at the top, with the <strong>Errors & Warnings</strong> table identifying any events that are WARNING, ERROR, or CRITICAL ERROR in severity. In this example, the WARNING severity level is due to ISAPI RESTRICTION. The image that you tried to load was %windir%\system32\inetsrv\asp.dll. </p> <p>6. Open the raw XML file directly by using a text editor, and look at the contents of each event. </p> <h2>Summary </h2> <p>You have completed two tasks: configured failed request tracing to capture traces for <em>*</em> if IIS returns it with a 404.2 status code; and verified that IIS captured the trace for your request. You also verified that the freb*.xml log file did not contain any other requests for the requests that you made because the requests did not have a 404.2 return code. When you consult the failure log file, you determined that the cause of the failure was that the extension was disabled for that request. You can try other non-HTML pages (like gifs or jpgs) and note that the log file does NOT add these traces. You can also easily change this to be 404, or capture the failure if the request takes longer than 30 seconds by setting the <em>timeTaken</em> field in your failureDefinitions. </p> <h2>Restore Your Backup </h2> <p>Now that you have completed the tasks in this article, you can restore the backup of the configuration. Run the following command with administrator user rights: </p><pre><code></code> <pre class="code language-SOMETHING"><br>%<em>windir</em>%\system32\inetsrv\appcmd restore backup cleanInstall<br><br></pre></pre> <p mce_keep="true"> </p></samp><br/><br/><a href="https://web.archive.org/web/20130320194905/http://forums.iis.net/1052.aspx" class="btn">Discuss in IIS Forums</a><aside id="author-info" class="about-author"><h1>By IIS Team</h1><p><img src="https://web.archive.org/web/20130320194905im_/http://i1.iis.net/avatar/IISTeam.jpg?cdn_id=2013-03-12-001" alt="IIS Team"/>The IIS team is a close-knit group of passionate individuals who are enthusiastic about web technology.
