When I started working on sharepoint 2010 initially, suddenly I got error as shown below,

Module IIS Web Core
Notification Unknown
Handler Not yet determined
Error Code 0x800700b7
Config Error There is a duplicate ‘system.web.extensions/scripting/scriptResourceHandler’ section defined
Config File \\?\C:\inetpub\wwwroot\wss\VirtualDirectories\80\web.config
Requested URL http://websitehost:80/SitePages/Home.aspx
Physical Path
Logon Method Not yet determined
Logon User Not yet determined

Above issue screwed up my head, I spent couple of hours on it and finally I got the solution.  Some reasons behind these issues are

  1. You might changed “sharepoint – 80” application pool’s .net framework version 2 to 4
  2. You might have the web.config file in your site or sub site it contains the duplicate section of scriptresourceHandler,  You should retain this section only on root web.config file.
