DHCP Alternate Configuration PowerShell Module

DHCP Alternate Configuration PowerShell Module

Description

There is currently no documented API for managing the DHCP client alternate configuration. Hence this module reads from / writes to the Windows Registry directory. The settings are saved in the value ‘Options’ under the key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Dhcp\ Configurations\Alternate_.

The config saved there needs to be set to active. This is done in the value ‘ActiveConfiguration’ under the key

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\services\Tcpip\ Parameters\Interfaces<NICID>

This module provides cmdlets to retrieve, remove and set the DHCP clients alternate configuration. The value ‘Options’ is a binaray value. The length varies from 48 to 128 bytes, depending on the settings made. The format of the value is documented in the function GenrateConfigBytes.
