I just purchased a new computer with Windows Vista Ultimate. I had a heck of a time figuring out how to configure the Remote Desktop Connecting feature using a Linksys router. When I finally figured it, I made a web page to show how to do it. Click here for the instructions. You'll need Microsoft Windows XP Professional or Windows Vista Ultimate for the feature to work. It's a neat feature. You can log unto your computer from anywhere in the world and it's like having you computer right in front of you.
