Advanced Configuration Parameters for DHCP

This section presents configuration parameters that affect the behavior of DHCP servers and clients, and that can be modified only through Registry Editor. For the changes to take effect after you modify any of these value entries, you must restart the Microsoft DHCP Server service for server parameters or the DHCP Client service for client parameters.

Caution You can impair or disable Windows NT if you make incorrect changes in the Registry while using Registry Editor. Whenever possible, use DHCP Manager to make configuration changes, rather than using Registry Editor. If you make errors while changing values with Registry Editor, you will not be warned, because Registry Editor does not recognize semantic errors.
