Exchange 2010 OWA : blank screen on logon

After you installed Exchange 2010 (with or without SP1) out-of-the-box, you might run into a blank screen on Outlook Web App login.
Outlook Web App redirects to the following URL:


Reason :
The exchange installer does not install all necessary prerequisits.

-Open the windows powershell (run as administrator)
-Enter the following commands:
1. Import-Module ServerManager
2. Add-WindowsFeature NET-Framework,RSAT-ADDS,Web-Server,Web-Basic-Auth,Web-Windows-Auth,Web-Metabase,Web-Net-Ext,Web-Lgcy-Mgmt-Console,WAS-Process-Model,RSAT-Web-Server,Web-ISAPI-Ext,Web-Digest-Auth,Web-Dyn-Compression,NET-HTTP-Activation,RPC-Over-HTTP-Proxy -Restart

OWA will now run properly again.
