Users group is a built-in group in Microsoft Windows NT and Windows 2000. The Users group is a local group that exists on all servers and workstations running Windows NT.
In Windows 2000, however, the Users group is a domain local group on domain controllers and a local group on member servers, stand-alone servers, and computers running Windows 2000 Professional.
The initial membership of the Users group is the domain users global group (all ordinary users on the network). The Users group has no preassigned rights or permissions and should be assigned permissions to network resources that ordinary users will normally require.
