The service in Microsoft Windows 2000 and Windows NT that implements the client component of the Dynamic Host Configuration Protocol (DHCP) on workstations and servers.
You can use the DHCP client service to obtain IP addresses and other TCP/IP configuration information from a DHCP server (such as a Windows 2000 or Windows NT server running the DHCP Server service).
Microsoft Windows includes support for DHCP and provides client software that lets you manage a machine’s IP address over a network. This software runs as a service under Windows 2000 and Windows NT. DHCP simplifies the administration and management of IP addresses for machines on a TCP/IP network.
