If the client workstation cannot locate the DHCP server on the network automatically, you will see an error message to that effect when you restart the client workstation.
DHCP can, however, manage much more than the IP addresses of client computers. It can also assign DNS servers, gateway addresses, subnet masks, and many other tasks.
In the Windows family of operating systems, only computers running Windows NT Server 3.51 or later can act as a DHCP server; a computer running Windows 98 cannot be a DHCP server. In the Novell world, NetWare 4.11 comes with DHCP as a standard service. In NetWare 5, this service is administered using a Java-based snap-in module for the administrator utility called the DNS/DHCP Management Console.
