Windows XP - Port 80 blocked

[derek.doerr]

I'm trying to install Apache onto my windows laptop. I keep getting a
message indicating that some other process has already bound to port
80. I don't know of anything else that explicitly listens on port 80,
so how do I determine what has bound to port 80?

in a command prompt: netstat -ano

this gives you all listening sockets and the PID of the application that
sits on it. Then you kan use tasklist to get the name of the application

netstat -anb
can give you the name directly in netstat, if you have SP2
