Managing Domain User Accounts

The next part of this tutorial is dedicated to helping you plan, manage, and administer user accounts in a secure and efficient manner. Microsoft Windows operating systems have come a long way since the early days of Windows Server and you have many options for managing users in Windows Server 2008.

Types of Users

It is a good idea to have a solid grasp of fundamental concepts that underpin the managing of users. In the first part of the tutorial, describe the types of users Microsoft Windows Server 2008 defines.

  • User: In Windows Server 2008, you can have local user accounts or domain user accounts. On a domain controller, local users and groups are disabled. In Active Directory, the domain user account contains user name, password, the groups of which the user is a member, and other descriptive information, such as address and phone numbers, as well as many other user descriptions and attributes, such as security and remote control configurations.
  • InetOrgPerson: InetOrgPerson is a type of user introduced in Windows Server 2003. InetOrgPerson has attributes based on Request for Comments (RFC) 2798, such as vehicle license number, department number, display name, employee number, JPEG photograph, and preferred language. Used by X.500 and Lightweight Directory Access Protocol (LDAP) directory services, the InetOrgPerson account is used when you migrate non-Microsoft LDAP directories to Active Directory. Derivative of the user class, the InetOrgPerson can be used as a security principal. The InetOrgPerson is compatible with X.500 and LDAP directory services.
  • Contact: Sometime you may want to create an account that will only be used as an e-mail account. This is when you would create a contact. It is not a security principal and does not have a security identifi er (SID). There are neither passwords nor logon functionality available with a contact account. However, it can be a member of a distribution group.
  • Default: user accounts These are the built-in user accounts created when a Windows Server 2008 installation or stand-alone server is configured to be a domain controller and Active Directory is installed. It is a good idea to rename the Administrator account for security reasons. The default user accounts are found by opening Active Directory Users And Computers, then examining the contents of the Builtin and Users containers. They include the following accounts:
    • Administrator: This is the account that has full control over the computer or domain. You should have a very strong password for this account. The Administrator is a member of these groups: Administrators, Domain Admins, Domain Users, and Group Policy Creator Owners. In a forest root domain, the Administrator is also a member of the Enterprise Admins and Schema Admins groups. The Administrator account can never be deleted. However, you can disable it or rename it. Either of these actions is a good practice to ensure a secure domain and network.
    • Guest: The Guest account can be used by users who don't have an account in the domain. It is a member of the Guests domain local group and the Domain Guests global group. The Guest account is disabled by default when you make a stand-alone Windows Server 2008 server a domain controller.

Naming User Accounts

Think about the naming scheme you plan to use for user accounts. As the organization changes and grows, the original naming scheme may need to change but not the need for a naming scheme of some kind. Although account names for operating systems earlier than Windows 2000 are limited to 20 characters for a user name, Windows Server 2003 and Windows Server 2008 have a 256-character limitation for a user name. Small organizations commonly use a person's first name and last name initial for their user account. In a larger organization, it may be a better idea to use their full name for their user account name.

This becomes a problem when an organization has more than one John Smith who needs a user account. Full names are likely to be an issue; using middle name initials can solve it. However, administrators may implement a numbering system. Keep in mind that although a user name can be 256 characters in length, a name of this length really isn't practical in most cases.
