Technical warning: this may make your eyes glaze over unless you're a techie type. :-)
Every once in a while I have to learn something I didn't expect to learn, but which, upon its accomplishment, makes me feel very pleased that I was able to find out about something so useful and share it with others who might be having the same problem.
I was installing WAMP today, which basically turns my computer into a server that is then able to process websites under development. This gives me the ability to try out coding on a test server without disturbing a live site. This is something I've been wanting to do for a while, and now with all new sites being created in Content Management Systems it's become pretty much a necessity. Plus, I want to be able to write some code for various reasons and this way I can test it without having to be online. Much more convenient.
Despite following all instructions I found, I could not get WAMP to work for me. I went to the forums and looked for solutions, finding a list of things to check. I went through that list and amde sure I did everything suggested, but was still not having any luck. The key to Wamp's functioning correctly had to be use of port 80, it was the only thing left. I needed to use port 80 for WAMP, and something had to be blocking it. I had closed down all the programs I had running that it was suggested I close down, but the problem was still the same. I needed a way to find out what was running on port 80.
My research on the web paid off, and I finally discovered how to find out what's using what port on my computer. It involved a Windows utility named "netstat".
Here's how to find out what's using port 80 (or any other port) in Windows XP:
