I have 4 computers on a network all setup with basic sharing. I have a desktop and wireless notebook with vista. I have a desktop and notebook with xp. I want the xp desktop to share it's folders and it does however it requires the other three computer to enter a username and password. The xp desktop can access all the other computers without anyproblems. All of the computers can share with each other without anyproblems. The xp desktop share permissions are set up to share with everyone to do everything. HELP!!!!!!! I have never encountered anything this bizarie and would greatly appreciate a genius right now. thanks.
