Summary

Dynamic Host Configuration Protocol is used to configure the hosts on a TCP/IP network. DHCP is the configuration service used by Windows NT. It allows the administrator to centrally control all TCP/IP configuration parameters including the IP address. With DHCP, addresses can be dynamically assigned.

The range of addresses that are available for dynamic assignment by a Windows NT DHCP server is called a scope. The scope is configured by the system administrator using the DHCP Manager software. The administrator defines the range of addresses in the scope, those addresses in the range that should be excluded from dynamic assignment, and the length of the time allowed for an address lease.

The DHCP Manager is also used to define DHCP options. DHCP options are the TCP/IP configuration values passed to the client.

In the next chapter we configure another server that is commonly found on a Windows NT network: the Windows Internet Name Service (WINS).
