Troubleshoot IIS Issue

Do I need to configure anything else in the Web.config file or in the IIS server?

Answer 1

It seems like you don't have Windows Permission to read the Web.config file and I believe, you don't have to change anything in the Web.config file.

In IIS server, add a user IIS_IUSRS using the security tab in the edit permissions sections. It'll allow all the user to access that file. If you ask about the IIS_IUSRS, it means when a web project is run on the IIS server, it associates the application pool with a user like local system, network services. So make sure about it.
