Converted to topic from comment on https://voice.unifysolutions.net/knowledge-bases/8/articles/2724-unifynow-installation-prerequisites#comment-20240
When following https://voice.unifysolutions.net/knowledge-bases/8/articles/2722-configuring-unifynow-for-use-with-iis on a new Win2016 host I discovered the ASP.Net 4.6 ISAPI filters were missing. On this same page there is mention of the (optional) Windows Authentication feature being required with the IIS role installation, but nothing about ASP.Net 4.6.
Circling back to this prerequisites page I can see that the IIS prerequisite is not discussed at all … and this may explain why I am still finding sites running under Cassini, particularly in PRODUCTION. I believe that the IIS install should be the default for any Enterprise installation of either UNIFYNow or UNIFYBroker, and have had this stance for some time. However I can see that the documentation could assist in guiding the installer to this model by listing the IIS (including ASP.Net 4.6 and Windows Authentication) prerequisites on this page and encouraging this configuration over Cassini.
