I have a peer to peer network consiting of 3 64 bit dell PCs and two Mac Pros. Each Mac pro has 3 virtual xp systems. User accounts on all systems match (user name and password) and I understand that each account has a different user hash. When users log into one systems they typically navigate to an external Lacie drive on another systems. I have a problem with user accounts getting locked out on the distant PC. Password policy locks out after 5 failed attempts, but users get locked out after 1 failed attempt over the network. Any solutions? Will a server running AD solve this issue?
