A type of user account in Microsoft Windows NT that has a domain-wide scope. (These accounts are called domain user accounts in Windows 2000.) In Windows NT, global user accounts are created using User Manager for Domains and are stored in the directory database on Windows NT domain controllers.
In Windows 2000, domain user accounts are managed through the Active Directory Users and Computers snap-in. Global accounts allow users to take full advantage of the Windows NT Directory Services (NTDS).
Users who have global accounts can access resources anywhere in the domain, provided they have appropriate permissions for those resources.
User Manager for Domains creates global accounts by default. The other type of user account in Windows, the local user account, exists only within the directory database of the machine on which it is created. Use only global accounts for users when implementing Windows NT domains as your security model.
