DHCP (dynamic Host Configuration Protocol) is used to dynamically assign IP addresses to client machines. We are going to demonstrate how to configure this DHCP server on Windows Server 2012 R2. This tutorial is divided into following two parts:
- Part 1. Installing DHCP Server role on Windows Server 2012 R2
- Part 2. Configuring and creating IP address pool in order to distribute those addresses to client machines
Prerequisites
Before you proceed with setting up DHCP server on your Windows Server 2012 R2, you have to fulfill following four requirements for an installation and configuration to be successful.
- Administrator account has strong password
- At least one static IP is configured
- Current security updates from Windows Update are installed
- Firewall is turned off
Part 1: Installing DHCP Server
Step 1: Open Server Manager from task bar and click Add roles and features
