The most complicated business-computing issue I've had to deal with is setting up and maintaining an office server for a local area network. For starters, things can go wrong when you try to configure your network server.
Most networks use PCs as servers.
If you think desktop PCs can be confusing, wait till you try to configure one as a server. Both are closed boxes you configure from your PC using a browser such as Internet Explorer or Netscape. Both run the Linux operating system, though you don't have to know anything about Linux. Each can be configured using user-friendly menus. All the server software is built into the box.
