A user can't log in to a NetBoot client. What can I do to fix that?

• Check to see if the user can log in to other computers. If the user can log in to other computers, then the computer the user can't log in to may be connected to a Macintosh Management server the user does not have an account on. If there is more than one Macintosh Management server, make sure the user has selected a server on which he or she has an account.
• Open Macintosh Manager and make sure the user is a member of at least one workgroup.
• Open Macintosh Manager and reset the user's password.
