Answer 2

The .NET Framework 3.5 on Microsoft Server 2008 is its integral part and it can't be repaired. I was successfully running my sites on MOSS 2007 64 Bit Version (using .NET Framework 3.5). But when I started InPlace Upgrade of MOSS 2010 and successfully completed the migration till Contiguration Wizard. Then upon opening any SharePoint Site including Central Admin. I am getting the following error.

 

HTTP Error 500.19 - Internal Server Error

The requested page cannot be accessed because the related configuration data for the page is invalid.

Module IIS Web Core

Any further clues what to do ???
