    That is correct, CWA is not supported when collocated on the Front-End Server.  It should be installed on a separate server.  Because both services use the Default IIS Virtual Site the installation of CWA can break some of the Web Components features already on the Front-End Server.  Ideally 2 separate IP addresses should be used for the Web Components and CWA IIS sites, but again this is not a supported deployment.

    Did you ever get this resolved? I am having the same issue at a customer of mine and cannot seem to resolve it. Thanks!

    Have they deployed CWA on the Front-End server?

    I suppose CWA should not have to be installed on Front End...
    Am I wrong?
