Sorry if this has been asked before.

New to networking. Started a small home network with just two Win XP workstations and Netgear Pre-N wireless router. Tried to share the C: drive from one PC to the other. A few folders can be shared, others like the Windows folder and Program Files are not accessible. The message I get is that I don't have permission and to contact the Admin, but both workstations are logged in as Administrator. These folders can not be shared individually either: the checkbox option is grayed out.

Any way around this?
