You should ugrade the thing to XP, I.E. that will run on NT will be too old to visit most sites that a young kid would want to see. I have gotten XP on a PIII system with 512 that runs acceptable, just don't expect to do anything other than look at sites (no online games for example will work well). If you have NT on it, I'm guessing it's a PIII and not a 4.
