Also known as system rights, the system tasks that a user can perform on a Microsoft Windows NT workstation, on a server running Windows 2000 or Windows NT, or on a domain. These tasks include changing a server’s clock, rebooting the machine, logging on to the local console, and performing a backup.
A system administrator can view and modify Windows NT rights by using the Policies menu in User Manager for Domains. Windows NT built-in groups have predefined sets of rights assigned to them.
The following table lists the basic Windows NT rights and the users and groups that have them by default.
| Right | Users and Groups Who Have the Right by Default |
| Access this computer from the network | Administrators Everyone |
| Add workstations to the domain | Administrators |
| Back up files and directories | Administrators Backup Operators Server Operators |
