windows 2000 advanced server

The owner of the company wants me to setup a web server for all the web hosting (I work for an ISP) is this feasable. He wants to assign all the .com’s 1 ip address. I am assuming that I need to mess around with the active directory to set the permisssions for the ftp side. Is this correct or is there an easier way…. Can this be done at all???

thanks
