Fix SMS_PORTALWEB_CONTROL_MANAGER (Internal Server Error) in SCCM 2012

Good day
For some reason SCCM 2012 ( System Center Configuration Manager 2012) may report the following error:

Portal Web Site Control Manager detected PORTALWEB is not responding to HTTP requests.  The http status code and text is 500, Internal Server Error.

Possible cause: Internet Information Services (IIS) isn't configured to listen on the ports over which PORTALWEB is configured to communicate. 
Solution: Verify that the designated Web Site is configured to use the same ports which PORTALWEB is configured to use.

Possible cause: The designated Web Site is disabled in IIS. 
Solution: Verify that the designated Web Site is enabled, and functioning properly.

For more information, refer to Microsoft Knowledge Base.

The Fix is easy by using the following command:

aspnet_regiis.exe /iru

The Aspnet_regiis.exe file can be found in one of the following locations:

%windir%\Microsoft.NET\Framework\v4.0.30319

%windir%\Microsoft.NET\Framework64\v4.0.30319 (on a 64-bit computer)

When the user open his OWA, it seem that everything is OK, but when opening any folder or sometime messages it just display the error message "Your request couldn’t be completed. This may have occurred for security reasons".
NOTE: This problem wont happens when the users are using HTTPS

FIX:
The solution is editing the web.config file and change the requireSSL=”true” to “false” , see the steps below :

1. Find the Outlook Web App Web.config file on the Client Access server. The default location is \Program Files\Microsoft\Exchange Server\EXCHANGEVERSION\ClientAccess\Owa.
2. Make a backup copy of the file (Important!)
3. Open the original file using Notepad. (You may need to run it as Administrator)
4. Find httpCookies httpOnlyCookies=”false” requireSSL=”true” domain=”” and change the requireSSL flag to false.

Save and close the file.

For the new settings to take effect, open a Command Prompt window, and then type iisreset to restart IIS using the command iisreset /noforce
