Create User Account For Home Network User

Hi,

How do I create an account for use by another PC on a home

network? We have XP Pro, XP Home, and Vista Premium

PCs that need to read from and write to files on other PCs.

Currently, I get privilege violations when I try to read on some

folders and can read some folders but not write to them.

Sharing appears to be set up the same on all folders.

(Privileges and user accounts differ. Not sure why.) As I

understand it I need an user account to set privileges for

access over the home network.
