If you have a peer to peer network, 3 work stations. The work group was created on all 3 work sations. The same two people have accounts on all three windows xp home ( 1 is actually prof.), though the login names vary like different dirivatives of the first and last names. I added one new account that is the same on all three work stations. When browsing shared folders on the other workstations from across the network, some folders I can open some say insufficent rights ask your administrator. All the w/s are wi/fi with using a netgear wireless router. I have not changed any settings in the router( like adding the name of the new workgroup), the w/s are pulling their ip / gateway from the routers dhcp.
