If your windows XP Professional based PC is connected to a domain, you can not add a user to the domain. This must be done on the server, and added in the active directory. If you just want to add a user ( not on a domain ), then go to START - SETTINGS - CONTROL PANEL - USER ACCOUNTS
Are you wanting to add a Mac to your Windows Active Directory domain? Is that what you mean by workgroup?

LDIFDE is a robust utility. This utility enabled you to import/export information from/to Active Directory. LDIFDE queries any available domain controller to retrieve/update AD information. Ldifde creates, modifies, and deletes directory objects on computers running Windows Server 2003 operating systems or Windows XP Professional. You can also use Ldifde to extend the schema, export Active Directory user and group information to other applications or services, and populate Active Directory with data from other directory services
Run this command at the command prompt:net user username password /add /domain
The following command-line tools can be used to manage Active Directory CSVDE Import and export Active Directory data using comma-separated format. Dsadd Add users, groups, computers, contacts, and organizational units to Active Directory. Dsmod Modify an existing object of a specific type in the directory. The types of objects that can be modified are: users, groups, computers, servers, contacts, and organizational units. Dsrm Remove objects of the specified type from Active Directory. Dsmove Rename an object without moving it in the directory tree, or move an object from its current location in the directory to a new location within a single domain controller. (For cross-domain moves, use the Movetree command-line tool.) Dsquery Query and find a list of objects in the directory using specified search criteria. Use in a generic mode to query for any type of object or in a specialized mode to query for for selected object types. The specific types of objects that can be queried through this command are: computers, contacts, subnets, groups, organizational units, sites, servers and users. Dsget Display selected attributes of specific object types in Active Directory. Attributes of the following object types can be viewed: computers, contacts, subnets, groups, organizational units, servers, sites, and users. LDIFDE Ceate, modify, and delete directory objects. This tool can also be used to extend the schema, export Active Directory user and group information to other applications or services, and populate Active Directory with data from other directory services. Ntdsutil General purpose Active Directory management tool. Use Ntdsutil to perform database maintenance of Active Directory, to manage single master operations, and remove metadata left behind by domain controllers that were removed from the network without being properly uninstalled.
When you install Active Directory on a server, you promote the server to the role of a domain controller for a specified domain. When completing this process, you are prompted to specify a DNS domain name for the Active Directory domain for which you are joining and promoting the server.If during this process, a DNS server authoritative for the domain that you specified either cannot be located on the network or does not support the DNS dynamic update protocol, you are prompted with the option to install a DNS server. This option is provided because a DNS server is required to locate this server or other domain controllers for members of an Active Directory domain
I do not understand the last portion of your question. I am hoping that you have a dedicated Windows System Administrator to setup this network for you, AND and that servers will be local within this network. If the servers will be scattered geologically please note there might be firewall issues, you will need to change this on the appropriate network hardware. First start by creating the domain, you will be able to do this within active directory, the change the servers to the domain via Computer > Properties > Computer Name, you will need to make a computer placeholder within active directory for each additional computer/user you add tot he domain. Please reply back with questions and clarification on your question, we will be able to assist you further. Thank you! Shaun B. Nuphonicblue at Gmail
