The configuration section 'system.servicemodel' cannot be read because it is missing a section declaration
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).
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.
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.
I'm hoping there are some experts here, who know how to fix this.

I had the same error message, and it was because I was missing the .NET 3.5.1 framework on that server. Enabling that fixed my problem: http://blogs.msdn.com/b/sqlblog/archive/2010/01/08/how-to-install-net-framework-3-5-sp1-on-windows-server-2008-r2-environments.aspx
