A: After configuring the System Center Configuration Manager 2012 Web Portal, when you try to access it by using the default address of https://savdalcm12.savilltech.net/CMApplicationCatalog, an error is returned: Cannot connect to the application server, which the screen shot below shows

The solution is to install WCF Activation and HTTP Activation. This is performed through System Center Server Manager.

Go to Add Features, .NET Framework 3.5.1 Features, WCF Activation (see screen shot below).

After the WCF Activation and HTTP Activation is installed, trying to access the site will now result in a different, and worse, error (I know, this doesn't seem like progress).

The solution is actually easy. The problem is caused because the WCF HTTP activation was installed after IIS and the .NET Framework. You just need to register the ASP.NET with IIS using the ASPNET_REGIIS.EXE tool:

C:\Windows\Microsoft.NET\Framework64\v4.0.30319>aspnet_regiis.exe -iru
 

You'll see the following:

Start installing ASP.NET (4.0.30319).
......
Finished installing ASP.NET (4.0.30319).


The website should now work fine (see screen shot below).
