Remote Access to your computer.

[Equinox Jr H2O]

I have a laptop running Windows 7 Home Premium and a desktop running Windows 7 Professional. I have connected both of them to the same network and workgroup so they can share files back and forth.
I then set up Remote Access on both computers so I should be able to access either one from either computer. This is where my problem begins.
I can access the desktop via laptop.
But I can't access the laptop via desktop.
Also if someone is already logged in they'd get logged out when I access or I'd have to cancel the connection.
My questions are:
1. How do I set up a remote connection that lets the user stay logged in as well?
I will be going away to college soon and my parents use the desktop. They aren't as computer literate as me and will require my assistance so I'd like to help them by remote accessing but still having them logged in so they can see what I'm doing exactly. (Something like Team Viewer but not exactly that.)
2. How come my desktop can't connect to my laptop?

If you are going to be using it while away from home, consider installing VNC on both the machines. You take-over the desktop, rather than login remotely. This way they can see what you do and learn from you :)

I was thinking about that. Problem is the free edition lets me do nothing and the enterprise edition (The one I really want) costs $50 per license and it doesn't state how many computers I can use it on.

TightVNC is a free, open source alternative. It does the same thing, just does it for free.

I'm getting now and will be testing later on today. If it works YOU ARE A LIFE SAVER!
