    you have 2 options. You can add 2 entries for WWW in DNS and it will alternate handing out the different entries or you can setup NLB (Network Load Balancing) which is part of Windows 2003 and will allow you to have more control over the balancing. You could specify one server as a failover or adjust a percentage split between the servers (50/50, 60/40, or whatever)

    There are some 3rd party applications to sycnrhonize IIS servers ( or you would have to create your own scripts to try to synchronize the data. There is a case study from microsoft on how they keep their IIS servers in sync (

    It will really depend on how often your site is updated. I currently have an internal website running on 2 servers with NLB and synchronize them with ROBOCOPY. But they are only updated once a week if that. It does get to be a pain everytime I need to do something simple like create a virtual directory and have to do this on both machines each time.

    Hi, Microsoft application center is another great (but more pricey) solution to do that.

    For synchronising the files on the servers, you can use Distributed File System and the File Replication System that comes with Windows Server 2003. It is a bit of a pain to set up, but it works and it's part of the Win2k3 package.

    If you've got the Mark Minasi book on Win Server 2003, he explains how to set it up in chapter 11.
