I would like to create an intranet site

What I want to do is create an intranet site where network users can go to access company information. I want to put out a monthly newsletter, service manuals and whatever comes to mind on the site. I have a server that is running IIS, and we access an existing intranet site to do our timesheets, expense reports, and other things tied to our accounting system that was set-up by them. To access the site we type: http://servername/sitename. I want to do just this with an intercompany website. I am using Frontpage to design the site, but I need help and instruction on publishing it to the server. Many thanks, Pat……
