setting up remote desktop for the internet

If you have Windows XP Professional™ and are not using its Remote Desktop functionality, you're missing out on one of its best features.  I've used Remote Desktop for years (since NT4 Terminal Server edition) and each generation has shown remarkable improvements in both performance and functionality.  Windows XP Professional™ is no exception.  With 24-bit color and passthrough audio it's as if you're sitting in front of the machine.  Home Edition users can get a taste of remote desktop with Remote Assistance.  Remote Desktop is also included in Windows XP Media Center 2005 edition.

A word of caution: Remote Desktop truly is a "professional" feature.  Exposing this kind of functionality over the Internet poses serious risks.  You should never enable remote desktop when you have easily guessable usernames or passwords.  I'd recommend only turning it on while on vacation, or away on business to limit your exposure.
