Linux as well, but you may have a little learning curve. Win2000 will work, but with more overhead.

Most here like Ubuntu Linux. I am familiar with it, but don't use it as I use either Slackware or Redhat for customization and the fact that I have been involved with both communities for 10+ years now.

Linux is great for file servers storing Word, Excel, music... Unfortunately, it falls short with certain apps that you would likely see in a corporate environment. There are problems with QuickBooks. Any corporate app that needs to have a server install, would never work. Law offices are a good candidate for Linux as are architectural firms. Most doctors offices can run Linux and not have issues as well.
