Thank you very much for this response, I was hoping to get this type of help to find this info. It turns out I think my error was clicking on a button to start the debugging server in Coldfusion Builder, perhaps in the RDS window. Earlier in the debug setup where you are to choose a server, none were in the select box. I thought if I clicked to start the server it would then show up in select box. In doing so I apparently started in instance of apache which then began intercepting the local browser requests but didn't have any paths set up to the files. I think it was solved by a computer restart though I tried other things such as shutting down the coldfusion services, rebooting, then starting them one at a time and trying to get to the administrator. I think I could have skipped most of that and saved some time and angst. Appreciate your response.
