Arc GIS Portal, Web Adaptor (Java Platform) and the problem of both IIS and Apache using the same port 80. How do I fix this?

I have ArcGIS Server and Portal running on Windows 8 (for development purposes only while we wait for our server).

In order to install Portal, I had to use ArcGIS Web Adaptor (Java Platform) because Windows Authentication (one of the items in the Web Adaptor installation checklist) is not available for my OS - Windows 8 (I am not using Windows 8 Professional or Enterprise).

I have installed the Web Adaptor and Portal and configured ArcGIS Portal.

I am able to successfully use https://mydomain.org:443 or https://mydomain.org:443/arcgis/home. The first takes me to Tomcat and the second to Portal. However, when I use http://mydomain.org:80 or when I am redirected to a http (not https) inside Portal I get an error message.

It seems to be happening because both IIS and Apache are using port 80.

How would I fix this?

Any advice would be greatly appreciated.
