XP Pro Small Network Access Query
 

I have two pcs on a small home network. The main pc runs on XP Pro and allows the other (running XP Home) to access various files as well as a second hard drive on my machine. My problem is not with the network, but with the access on my pc. My son has a screen name on my pc and when he is logged on he can access the second hard drive through My Computer I need the second machine to be able to access this drive, but not my son when he is logged onto my pc under his screen name. Any help gratefully appreciated.
