You first said when you try to surf to yur url you get 404 error.
I told you to telnet localhost 80 GET / but you told me no error in the ascii output. And you also said socket cannot bind to port 80. So I really assumed that another webprocess started up before apache did. Because when you telnet to port 80 and GET / if you dun see an ascii output of the error page that means port 80 is really in use and a webserver is running. But you never pasted the output here so I assumed you don't want to reveal too much info abt your site, fair enuf, thats why I told you to go into /etc/init.d directories to do a quick check to see if there is a startup script for another possible http webserver application.
I'm assuming here that your apache installation is 100% perfect and that you previously able to bring up and use your webserver but now couldn't probably due to some network related or config issue which causing your problem. if my assumption is wrong you better say so because from what I gather you dun seem to know very much abt the server you are managing even when I told you to grep you use a non-root account to do it which strikes me as quite odd.
anyway I'm thinking 2 more possibilities here.
Go to your webserver, open up the web browser on the server and type
http://localhost
and see what you get? Do you see your webpage or do you see another webpage?
The other one is quite remote but sometimes can be affected. Clear your browser cache delete all the cookies or go to another PC and try to surf to the website.
