Assuming you want to RDP from n900 as client into your PC as server ... Vista home basic can't run RDP server, you can only do that with the pro versions. It's posible to circumvent this, but you'd need to do some googling elsewhere if oyu wnat to go down that route. No such problem using VNC however so that's another alternative, there's loads of detailed help here about VNC setup if you do a search.
