This may sound obvious, but try the Windows Help Files. They have lots of great information. And you can always check out the appropriate Microsoft Windows Home page, or newsgroups. The thing I discovered with Windows 2000 Professional is that most of the other Windows 2000 users know this is for Professionals, and you're supposed to already know this stuff if you have Windows 2000 Pro. That's one of the reasons I now have Windows XP.
