title: The configuration section 'system.servicemodel' cannot be read because it is missing a section declaration
body: <p>I have somewhat of a problem.
  My old webserver (windows 2003) have been replaced, with a 2008 R2. I have been given an admin account on it, and can do whatever I want, but I am no expert on this area.
  I configured the roles to have application developement and Web server (iis7).</p>
  
  <p>BUT, my website runs .NET4, and the role only installed 3.5.
  So I have attempted to install .NET4 manually, on the server.
  My problem is, my website will not work on it, due to the System.ServiceModel section in my web.config.
  I have made sure it runs in .NET4 application pool.</p>
  
  <p>I assume this is a WCF problem, but I can't grasp how to solve it. I have tried everything I found on google. 
  aspnet_regis, ServiceModelReg.exe and so on.
  I have even tried re-installing the webserver role, but I still get this error, everytime I try to enter the sites setup.</p>
  
  <p>I'm hoping there are some experts here, who know how to fix this.</p>
