We applied the patches released by MS for .Net 3.5, 3.0 and 2.0 which are released in last week of June. After applying it and restarting server MOSS Administrations sites and application sites were not opening. I reconfigured the Administration site. After that It started working, but my Application sites are still giving below error- --- Configuration Error Description: An error occurred during the processing of a configuration file required to service this request.

Hi, Looks like your running ASP.NET 1.1 and needs to be changed to 2.. The ASP.NET IIS Registration tool (Aspnet_regiis.exe) allows an administrator or installation program to easily update the script maps for an ASP.NET application to point to the ASP.NET ISAPI version associated with the tool, when multiple versions of the .NET Framework are executing side-by-side on a single computer. You can also use the ASP.NET IIS Registration tool to view information about ASP.NET. To list the status and installation path of all of the versions of ASP.NET that are installed on your computer, use the -lv option. If you want to see the paths to all of the IIS metabase keys where ASP.NET is mapped, use the -lk option. If SharePoint is the only application installed on the Server and you do not need ASP.NET 1.1. The following command installs the and updates the script maps of all existing ASP.NET applications. Note that only applications that are currently mapped to an earlier version of ASP.NET are affected. %Windows%\Microsoft.NET\Framework\v2.0.50727\aspnet_regiis.exe –i The following command installs the script maps of the application and all subdirectories: %Windows%\Microsoft.NET\Framework\v2.0.50727\Aspnet_regiis -s W3SVC/<YourWebSiteID>/ROOT I would prefer to run aspnet.regiis.exe -i as this will set all applications to use ASP.NET 2. Hoqwever, it depends on if you are running applications that require ASP.NET 1.1. As always please ensure you have a backup of the environment -IvanIvan Sanders My LinkedIn Profile, My Blog, @iasanders.
