For a selected computer you can view a list of connected users, view shared and open resources, manage directory replication, manage the list of administrative alert recipients, manage services and shared directories, and send messages to connected users. Select a Windows NT 4.0 domain, workgroup, or computer to administer.To manage Windows Server 2003 domains and computers, use Active Directory and the other Windows Server 2003 administrative tools instead.

Server Manager is a Windows Server 2003 tool you can use to manage Windows NT 4.0 (or Windows NT 3.51) domains and computers.
