I'm not sure I even know how to ask this question. For the past two years I've been developing websites on my Windows XP PC. I develop in either ColdFusion or PHP. I've been running IIS and ColdFusion app server. Everything working fine.
In Dreamweaver, if I'm developing in PHP or in ColdFusion, I can preview in browser by hitting F12.
This past week, I was doing a proof-of-concept for a client, with the help of a vendor, and their software runs on the ASP.NET platform. We installed all the necessary "stuff" on my pc and ran the vendor's software.
Now I'm back to doing my own development again and now when I try to preview in browser in Dreamweaver, it doesn't work. If I'm trying to preview a PHP page, Firefox asks me if I want to save or open. If I'm tyring to preview a Coldfusion page, Firefox displays an error: "Server Error in '/JrunScripts' Applicaton. The resource cannot be found. HTTP 404 .. ." etc. The requested URL was "/JRunScripts/jrun.dll/index.cfm". And at the end of the error, there is "version information" that says "Microsoft .NET Framework Version 2.0.50727.3053; ASP.NET Version:2.0.50727.3053."
So I think that somehow my pc is trying to run the .NET framework? And so can't interpret the PHP or ColdFusion pages?
How do I "undo" this and get back to my normal environment? Unfortunately, the vendor isn't available since it's the weekend!
I've looked at the list of services that are started and nothing looks amiss there. I have IIS and my ColdFusion App Server running. There are two service with .NET in the name but neither of them is started: ".NET Runtime Optimization Service v2.0.50727_X86" and "ASP.NET State Service".
So I'm wondering if there is some configuration in IIS that maybe the vendor did that I didn't see?
I don't know anything about .NET and I don't know a whole lot about IIS, other than that I run it, and I change the home directory for the default web site depending upon which local site I'm working on.
