[Xitami] Port 80 mystery

[Toni McConnel]

I have just installed Xitami but when I try to start it, I get a message 
saying that Port 80 is not available because it is being used by another 
server.  I don't have a clue what it is, and doing searches for "server" 
and "localhost" only turn up Xitami stuff.  Can't find anything else 
that looks like a server to me.  There must be a way to look up 
something in the system that will tell what is using Port 80 but I don't 
know what it is.  The only idea I have is that I might have installed 
something with Dreamweaver as a test site a long time ago.  Can anyone help?
