A) Are you XP or 2000? Without a domain all logins are processed locally. Changing from one machine to another requires creating a new profile on that machine. RightClick My Computer and choose properties or use “System” in the control panel. In XP, User profiles are controlled on the Advanced tab, (like Performance and Statup & Recovery). That is location of the registry entry for local versus ‘roaming’. The kicker to this is user access (Who is allowed to login) is handled by “Users & Passwords” in the control panel. If the user is not listed there and you are not a domain then they should not logon successfully.
