Thanks, Arvind. Specifying the port as :81 did word sporadically. But the real issue was trying to run MS IIS and Apache at the same time. Both wanted that port. It was much easier to just shut down MS IIS and let Apache ru nit’s default settings.
Nelson & Dion, Thank you for your quick replies. While they didn’t deal directly with the specific port issue I was having, they lead me to a different path. I gave up trying to support both Apache and MS IIS and went with the flow. I shut down MS IIS and completely scorched the XAMPP and WP installs (my third) and started again with everything completely standard. It worked. I never did get to the root of the issue, but I can say that the standard install doesn’t work with IIS running. Thanks again for your help! – Bob
