Error parsing XML file in asp.net

If you have installed VS2005 before configuring IIS Server and then try to run an asp.net application on the IIS Server then it will give error:

Error parsing XML file. At line number 1

To rectify this error, we need to install a utility named aspnet_regiis –i (ASP.NET IIS Registration Tool) from the command prompt. It can be found here: %windir%\Microsoft.NET\Framework\v2.0.5027.
