by

PowerShell commands are an easy way to save a lot of time as system administrator. In this article, I'll show you how to configure DHCP from PowerShell. I have following information including scope, and router gateway IP.

DHCP

DNSServerIP="192.168.1.10"
DHCPServerIP="192.168.1.10"
StartRange="192.168.1.150"
EndRange="192.168.1.200"
Subnet="255.255.255.0"
Router="192.168.1.1"

Following is the configuration break down:

  1. Installing DHCP
  2. Adding DHCP scope
  3. Adding DNS server, and router gateway options
  4. Setting lease duration for a scope
  5. Restarting DHCP service

Step-by-Step Instructions
