Implementing Dynamic Host Configuration Protocol in Windows Server 2022

Introduction

Dynamic Host Configuration Protocol (DHCP) is a network protocol used to automatically assign IP addresses and other network parameters to devices on a network. DHCP is used extensively in modern networks, and is particularly useful in environments where IP addresses are assigned dynamically (i.e. on-demand) rather than statically (i.e. manually).

In this article, we will show you how to implement DHCP in Windows Server 2022. We will cover the following topics:

• Installing the DHCP Server Role
• Configuring DHCP Scopes
• Configuring DHCP Options
• Configuring DHCP Reservations
• Monitoring DHCP

Installing the DHCP Server Role

Before you can configure DHCP on your server, you first need to install the DHCP Server role. This can be done using the Server Manager console, or via PowerShell.

Installing DHCP using Server Manager

To install DHCP using Server Manager, follow these steps:

1. Open the Server Manager console and click on Manage.
2. Click on Add Roles and Features.
3. On the Before you begin page, click Next.
4. On the Installation Type page, select Role-based or feature-based installation and click Next.
5. On the Server Selection page, select the server on which you want to install DHCP and click Next.
6. On the Server Roles page, select the DHCP Server role and click Next.
7. On the Features page, click Next.
8. On the Confirm installation selections page, click Install.
9. On the Results page, click Close.

Installing DHCP using PowerShell

To install DHCP using PowerShell, follow these steps:

1. Open a PowerShell prompt and type the following command:

Install-WindowsFeature -Name DHCP -IncludeManagementTools

2. Press Enter to install the DHCP Server role and management tools.

Configuring DHCP Scopes

A DHCP scope is a range of IP addresses that are available for assignment to devices on a network. Before you can start assigning IP addresses, you need to create at least one DHCP scope on your server.

Scopes can be created using the DHCP console, or via PowerShell. In this section, we will show you how to create a scope using the DHCP console.

Creating a DHCP Scope using the DHCP Console

To create a DHCP scope using the DHCP console, follow these steps:

1. Open the DHCP console and expand the IPv4 node.
2. Right-click on Scope and click New Scope.
3. On the Welcome to the New Scope Wizard page, click Next.
4. On the Scope Name page, enter a name for the scope and click Next.
5. On the Scope Type page, select the Standard Scope option and click Next.
6. On the IPv4 Address Range page, enter the start and end IP addresses for the scope and click Next.
7. On the Add Exclusions page, click Next.
8. On the Lease Duration page, enter the lease duration for the scope and click Next.
9. On the Configure DHCP Options page, select the Yes, I want to configure these options now option and click Next.
10. On the DHCP Options page, select the Router (Default Gateway) option and click Configure Options.
11. In the Router (Default Gateway) Properties dialog box, enter the IP address of the default gateway and click OK.
12. Click Next to continue.
13. On the Configure DNSServers page, select the Yes, I want to configure these options now option and click Next.
14. On the DNSServers page, enter the IP addresses of the DNS servers and click Next.
15. On the WINS page, click Next.
16. On the Activate Scope page, select the Yes, I want to activate this scope now option and click Next.
17. On the Completion page, click Finish.

Configuring DHCP Options

DHCP options are used to provide additional configuration information to DHCP clients. These options can be used to specify the default gateway, DNS servers, WINS servers, and more.

Options can be configured using the DHCP console, or via PowerShell. In this section, we will show you how to configure DHCP options using the DHCP console.

Configuring DHCP Options using the DHCP Console

To configure DHCP options using the DHCP console, follow these steps:

1. Open the DHCP console and expand the IPv4 node.
2. Right-click on Scope and click New Scope.
3. On the Welcome to the New Scope Wizard page, click Next.
4. On the Scope Name page, enter a name for the scope and click Next.
5. On the Scope Type page, select the Standard Scope option and click Next.
6. On the IPv4 Address Range page, enter the start and end IP addresses for the scope and click Next.
7. On the Add Exclusions page, click Next.
8. On the Lease Duration page, enter the lease duration for the scope and click Next.
9. On the Configure DHCP Options page, select the Yes, I want to configure these options now option and click Next.
10. On the DHCP Options page, select the Router (Default Gateway) option and click Configure Options.
11. In the Router (Default Gateway) Properties dialog box, enter the IP address of the default gateway and click OK.
12. Click Next to continue.
13. On the
