Core handler (.ashx) 404

[Aarsh]

Hello,

I was observing our intranet site in fiddler2 and saw a 404 #Err for a core handler. May I please have any suggestion to narrow this problem, down ? I'm attaching the trace if that helps. this happens on most of the pages of our application but this screen shot is for /Dashboard/Dashboard.aspx page in specific.

Application is running on ASP.NET 4.0

Thanks in advance for any help / constructive suggestions ,
-Aarsh
