A new forum poster is running in to an old problem I have encountered several times before: something is already running on port 80. Does anyone know of any useful program(s) that list what ports are being used by what programs/processes?

You could use a port scanner and point it at 127.0.0.1

BTW, the problem in the other thread is likely Skype.

Any suggestions for XP? I tried nmap though it proved useless.

I have TCPView and now that I disabled resolved addresses it's a bit easier to read the port numbers. I see IIS and Apache with a bit more ease now.
