Starter has remote desktop, but you can only connect from that computer and not to it. So, you can remote from your netbook running starter to another computer running 7 Pro, Ultimate, or Enterprise (or XP Pro), but you can't connect from 7 Pro, Ultimate, or Enterprise (or XP Pro) to your netbook running starter.
It's all covered on the Microsoft website.
