Unable to setup client certificate authentication between two IIS applications

Hello,

I have two WCF applications that are deployed to IIS 8 on different machines. I am trying to setup client certificate authentication to authenticate the first application when invoking the rest services of the second application. I have followed many step-by-step guides online to do the setup for both applications. I have resolved many errors during setup but now I am stuck with a new issue anbd I can't seem to a find a solution for the problem anywhere online. 

The error is:

[HttpException (0x80004005): The HTTP request is unauthorized with client authentication scheme 'Anonymous'. The authentication header received from the server was ''.]

Step-by-step guide:
