ftp into your server. if the directory tree is /, send the files. if you see public_www or public_html you need to place the files in that folder. most publishing apps do this and you only need to tell it
http://www.server.com or ftp.server.com and user/pass. is this MS publisher?? it might need frontpage server extensions to be installed. do you have frontpage in your office suite, if so, make a very simple index.html and publish to see what happens.
