Arghhhh cant use remote desktop!!!!

Hello,

I read all the posts in this thread and can't truly find the answer to my problem. So, here is what I am having a problem with. I have a laptop that is running vista home basic and I want to use remote desktop to connect to a home pc that is running xp home. I have looked at both computers and remote desktop is on both but when I go to connect it won't work. I read that you cant use remote desktop from home to home but if that is the case then why is it on both computers? Also, when I go into remote and check the remote tab there is nothing there for me to add users. Can someone tell me what I am missing? Should I upgrade my laptop to Vista business and if I did that would I then be able to use remote desktop to access the home pc that is running xp home? Also, I am not that savvy when it comes to computers so if you could be so kind as to use layman terms :) I would certainly appreciate it!! Thanks in advance! KathyM
