I'm trying to figure out if IIS needs to be configured in any way for an ArcGIS Server 10.6.1 (Windows) setup that will NOT use the Web Adaptor? I haven't been able to find much documentation explaining this situation when Web Adaptor is out of the equation.
We are using our own reverse proxy server which is located in the DMZ. This is external facing and we want to use HTTPS Only. We don't use Web Tier Authentication.
