Windows Server 2012 and Office Web Apps Server
Posted by Chad McGreanor on November 2, 2012
If you have been using the following TechNet article and then wondering why your Web Apps Server that you are using for Lync is not working then you are not alone.
http://technet.microsoft.com/en-us/library/jj219455(v=office.15).aspx#before
The issue is that the pre-requisite software that is listed on the page does not include all the features that are required for the application to work correctly. The features missing are:
NET-Framework-Features, NET-Framework-Core, NET-HTTP-Activation, NET-Non-HTTP-Activ, NET-WCF-HTTP-Activation45
The full command for all features is:
Add-WindowsFeature Web-Server,Web-Mgmt-Tools,Web-Mgmt-Console,Web-WebServer,Web-Common-Http,Web-Default-Doc,Web-Static-Content,Web-Performance,Web-Stat-Compression,Web-Dyn-Compression,Web-Security,Web-Filtering,Web-Windows-Auth,Web-App-Dev,Web-Net-Ext45,Web-Asp-Net45,Web-ISAPI-Ext,Web-ISAPI-Filter,Web-Includes,InkandHandwritingServices, NET-Framework-Features, NET-Framework-Core, NET-HTTP-Activation, NET-Non-HTTP-Activ, NET-WCF-HTTP-Activation45 -source D:\sources\sxs
I have tested this and verified it does work. I have my entire Lync 2013 environment working on Windows Server 2012 including Office Web Apps Server J

Hi I have installed all pre-req defined above and also followed technet documentation to integrate Lync with office web app. However I am still getting ASP.net warning on office web apps server. I have restarted office web app and Lync FE server but same issue. Lync 2013 client cannot view power point presentations.Anything else that I might have missed. Any help will be appreciated.
OS is Windows Server 2012 RTM.

My issue was related to the specific features mentioned above not being installed. The TechNet documentation did not list them as required. Once I installed those features it all worked. You may try uninstalling the Web Apps Server and then installing again.
