MediaMaster works from the Unity Admin pages without Anonymous DCOM access enabled on the Unity server. It does not work from PCA without Anonymous DCOM access enabled. Enabling Anonymous user users to remotely execute code on a server does not seem like a valid option for me.
I believe the Admin pages for Unity run in IIS, the PCA pages are in TomCat. It seems to only be a problem with the Tomcat web server. I have not been able to narrow which files are being accessed when Tomcat fires up the MediaMaster.
Has anyone resolved this and if so how do I make the MediaMaster control bar function in PCA without enabling anonymous DCOM access?
