HTTP Error 500.19 - Internal Server Error issue with iis

I am getting following error from my hosted site

HTTP Error 500.19 - Internal Server Error

 55:                <add name="X-UA-Compatible" value="IE=edge" />

I gave the permission to the IIS_USR also in security and allow the windows authentication. Any idea to fix this

It looks like you may have duplicate key's in your configuration file based on: duplicate collection entry of type 'add' with unique key attribute 'name' set to 'X-UA-Compatible'

Search for "X-UA-Compatible" in your configuration file and make sure there is only one entry with this name.
