the limit is in the number of PC's that can connect to any one PC at the same time, not the number on the network. Look down the page here:
I have XP Home (Media Edition) & have recently learned that XP Pro allows up to 10 units to be networked where XP Home only allows 6. When I add one more unit, I will have used the 6. Can I use a hub or switch to overcome this limitation, or must I go to XP Pro?
