I have installed the Tracing feature and enabled failed request tracing for a website, to debug a Classic ASP website. The XML logs are created upon occurring errors, however when I open them in IE, instead of getting the nice blue interface I get a massive amount of code/text.
Why doesn't the interface load and how can I fix it?
I found out I was missing the freb.xsl file, so I downloaded one from here (link at the bottom of the page): http://blogs.iis.net/bills/archive/2006/10/19/Making-Failed-Request-Tracing-More-Approachable.aspx
Hope someone will find this helpful. :)
If the freb.xsl file is missing from the directory that contains the log files, then the nice interface won't show. Rather than trying to find a website with the latest freb.xsl, I found on this page:
that if you just delete the directory that the xml files are being written to (likely something like C:\inetpub\logs\FailedReqLogFiles\W3SVC1), then IIS will automatically recreate the directory and write the freb.xsl file when it next creates the next log file.
I had the same problem on a fresh install of Windows 2012. However, the freb.xsl file was present in the same folder as the event XML file.
To get it to show the 'nice interface' I had to add "about:internet" to the IE11 trusted sites list, as discussed here: http://forums.iis.net/p/1147605/1862016.aspx
I got the failed request trace to display in IE (and it doesn't work on chrome) by pointing an IIS website at the folder and open it in IE - version 11 - from there.
Other things I tried before this was
about:internetto trusted sites
I am certain this has to do with security settings and there is probably an easier way of getting this to work without IIS. I go with the path of least resistance on this one.
