Windows 2000 provides two types of user accounts: local user accounts and domain user accounts. With a local user account, an account is created in the local security database, with this type of account, a user has access to only the resources on that computer, this is typical in a workgroup. With a domain user account, a user can log on to the domain to access network resources. A user with a domain account can access all of the resources in the domain.

Local User Accounts

     To gain access to resources on a local computer, a user needs to have a local user account on the computer. There are two kinds of local user accounts: user-defined accounts and built-in accounts.

User-defined Local User Accounts

     User-defined local user accounts are those that an administrator creates to allow a user to gain access to only those computers where his or her user account exists. You cannot create user-defined local user accounts on a Windows 2000 domain controller. It is possible to have an account on the local computer and another account in the domain; however, the user can use only one of the accounts at a time.

Built-in Local User Accounts

     In addition to user-defined accounts, Windows 2000 provides two built-in user accounts to aid administrators in performing administrative taks and in providing users with temporary access to a local computer. Upon installation, Windows 2000 automatically creates two built-in user accounts - Administrator and Guest.


Domain User Accounts

     To access resource on the network, you need to use a domain user account. When a domain user account is created, it exists in Active Directory and is accessible from anywhere in the domain.

User-defined Domain Accounts

     User-defined domain accounts are those that an administrator creates to allow users to log on to a domain and access resources anywhere on the network. User-defined domain accounts are created on a domain controller. The domain controller replicates the new user account information to all domain controllers in the domain.

Built-in Domain User Accounts

     Windows 2000 provides two built-in domain user accounts - Administrator and Guest. These built-in user accounts are similar to the built-in user accounts available on local computers in workgroups. The main difference is that these accounts enable access to the entire doamin.



Groups

     A group is a collection of user accounts. You can assign access permisssions to all members of a group at one time, so that you do not need to assign the permissions individually. A group can exist on a local computer only, on computers within a single domain, or on computers across multiple domains.

Groups on a Local Computer

     On local computers (computers that are not domain controllers), you can create only local groups in the local security database. A group located on a computer that is not a domain controller provides security and access for the local computer only.

Groups on a Domain Controller

     On a domain controller, you create groups in Active Directory. A group that exists on a domain controller can include users throughout the entire domain or across multiple domains.
