Install and Configure DHCP Server on Windows Server 2019

In this article, we will learn How to Install and Configure DHCP Server on Windows Server 2019 Step by Step. We will also cover How to authorize a DHCP server; How to create and configure scopes.

In nowadays networks, the DHCP service is used by workstations, Preboot Execution Environment (PXE) network boot clients, printers, mobile devices (i.e. smartphone or tablet), IP-based phones, data scanners, etc. Each system must have its own unique IP address to communicate over the network. There are two ways to have clients and servers get TCP/IP addresses:

1. You can manually assign the addresses.
2. The addresses can be assigned automatically.

Manually assigning addresses is a fairly simple process if you have a fewer systems. Now think you are a network administrator and you have to assign IP addresses, subnet masks, default gateways, and all other configuration options needed to run the network on 2000 systems. Manually doing this is a nightmare for any network administrator and you can not expect the end-user to do the same. This is where DHCP comes into play.

DHCP Stands for Dynamic Host Configuration Protocol and its job is to centralize the process of IP address and network configuration option assignment.
