As an essential part of a DHCP Server, we create and configure a DHCP Scope to specify the range of IP addresses from which a DHCP server can assign one to a client in our subnet. That is the primary and well-known use of a DHCP Scope. There are multiple ways to create and configure a DHCP Scope in Windows Server OSs including Windows Server 2022. One interesting, easy, and yet professional method is using Windows PowerShell. Throughout this article, we will cover the steps to configure a DHCP Scope in Windows Server 2022 Using PowerShell.

To create and configure a DHCP Scope using the GUI method, read Create And Configure A DHCP Scope In Windows Server 2022 article.

DHCP Scope Configuration Steps Using PowerShell

Using Windows PowerShell, we just write the commands and run them directly. That means, we must know the related commands and have a good knowledge of working with PowerShell. This section will describe all the details to configure a DHCP Scope in Server 2022 using PowerShell in the below simple steps. Let’s dive into it.

Step 1: Open Windows PowerShell

In the Start Menu right-click on Windows PowerShell and choose Run as Administrator. Search for it if it is not available in the Start Menu. We can also open it from the Run by typing powershell in the Run dialogue box.

Step 2: Create a New DHCP Scope Using PowerShell

To create a new scope, we use the Add-DhcpServerv4Scope PowerShell command. Using this command, we need to specify the following four parameters:

• The first one is the scope name. We use the -Name parameter name followed by the scope name enclosed in the double quotation.
• Secondly, we specify the start of the range IP address using the -StartRange parameter name followed by its value (IP address).
• The third one is to specify the end of the rage IP address using the -EndRange parameter name followed by its value (IP address).
• And, the last one is to specify the subnet mask IP address using -SubnetMask parameter name followed by its address.

As of my new scope, the whole command becomes Add-DhcpServerv4Scope -Name "Office B" -StartRange 192.168.1.100 -EndRange 192.168.1.2 -SubnetMask 255.255.255.0 See the picture illustration below.

Step 3: Verify DHCP Scope Using PowerShell

Now that we have created our new DHCP Scope in step 2, we can verify it using the Get-DhcpServerV4ScopePowerShell command. Using this command, we can see a list of DHCP Scopes available on our DHCP Server. We can see the details for each of the scopes such as Scop ID which is most often used for further configuration of a DHCP Scope. See the illustration in the below image.

Step 4: Add Exclusion Range in a DHCP Scope Using PowerShell

To add a new Exclusion Range in a DHCP Scope, we use the Add-DhcpServerv4ExclusionRange PowerShell command. We specify the scope using the -ScopeId property. Then we use the -StartRange and -EndRange parameters each followed by the IP address that makes up the exclusion range. The command we used to create an exclusion range isAdd-DhcpServerv4ExclusionRange -ScopeId 192.168.1.0 -StartRange 192.168.1.150 -EndRange 192.168.1.160. Looking into it, we see that we have created an exclusion range that starts at 192.168.1.150 and ends at 192.168.1.160 in our scope with scope ID 192.168.1.0.

We can also verify the Exclusion Range(s) in a specific DHCP Scope. To do so, use the command Get-DhcpServerv4ExclusionRange. We should use the Scope ID with this command to point to our specific Scope. So, our command is Get-DhcpServerv4ExclusionRange -ScopeId 192.168.1.0. As we see, the picture below shows the exclusion range we just created.

Step 5: Set the Lease Duration Using PowerShell

Use the Set-DhcpServerv4Scope PowerShell command to set the lease duration. We must point to the scope using the -ScopeId parameter name followed by its value. Then we just specify the Lease Duration using the –LeaseDuration parameter name followed by its value. The format to define the Lease Duration value is day.hours:minutes:seconds. Saying those explanations, the whole command to define the Lease Duration, in our example, is Set-DhcpServerv4Scope -ScopeId 192.168.1.0 -LeaseDuration 10.00:00:00. Also shown in the below image. A duration of 10 days is defined for the Lease Duration in our example.

Now, to verify the Lease Duration configuration, use Get-DhcpServerv4Scope the command. By default, it is set to 8 days. But as we defined 10 days for it, we can see the changes.

Step 6: Configure the Default Gateway Using PowerShell

We can specify the Default Gateway for a DHCP Scope using the Set-DhcpServerv4OptionValue command. Like other steps, we need to point to the Scope using the Scope ID. We use the parameter name -Router followed by its value (IP address) to define the Default Gateway for a DHCP Scope. In our example, the complete command is Set-DhcpServerv4OptionValue -ScopeId 192.168.1.0 -Router 192.168.1.1. We set 192.168.1.1 as the Default Gateway address for our DHCP Scope.

We will verify the Default Gateway configuration at the end of the next step, as we use the same command to verify these two steps.

Step 7: Configure DNS Domain and DNS Server Using PowerShell

As the Default Gateway configuration, we use the Set-DhcpServerv4OptionValue PowerShell command to configure the DNS Domain and DNS Server. We can configure the three of them in one command line using their parameter names and their values. Use -DnsServer parameter name followed by its value (IP Address) to configure the DNS Server. Use the -DnsDomain parameter name followed by its value enclosed in double quotation to configure the DNS Domain. Remember to address the scope using the Scope ID properties. In my example, the whole command becomes Set-DhcpServerv4OptionValue -ScopeId 192.168.1.0 -DnsServer 192.168.1.2 -DnsDomain "Technig.com".

To verify the Default Gateway configuration, DNS Server configuration, and DNS Domain configuration, use the Get-DhcpServerv4OptionValue PowerShell command followed by the Scope ID properties. In my case, Get-DhcpServerv4OptionValue -ScopeId 192.168.1.0 is the whole command line.

That is all with the DHCP Scope configuration using PowerShell commands. We can do all the settings and configuration, which we could do with the GUI method, using PowerShell. This method may not be user-friendly, but it is a time-saving, professional and maybe elegant method.

Delete A DHCP Scope Using PowerShell

In addition to the above DHCP configuration steps, this is the appropriate point to describe how we can delete a DHCP Scope using Windows PowerShell. To delete a DHCP Scope, use the -Remove-DhcpServerv4Scope command followed by the -ScopeId properties. Considering the DHCP scope I work with, the complete command is -Remove-DhcpServerv4Scope -ScopeId 192.168.1.10. See the picture below.

Now, to verify if it is deleted, run the Get-DhcpServerV4Scope command and there will no longer be that scope available.

As simple as that, we can delete a DHCP Scope and verify the deletion using Windows PowerShell.

Conclusion

In a step by step approach, we covered how to configure a DHCP Scope in Windows Server 2022 using Windows PowerShell. We discussed the PowerShell command for creating a new DHCP Scope in an initial step. Then we went through the steps to add an exclusion range, the default gateway, DNS Domain, and DNS Server to a DHCP Scope all using the PowerShell command. Of course, we also verified each step. Lastly, we covered how we can remove a DHCP scope using PowerShell.

We have published a step by step guide on how to install and configure DHCP in Server 2022 using Server Manager. This article, in turn, covers an easy and step by step guide on how to install and configure DHCP in Server 2022 using Windows PowerShell. Using PowerShell to perform such technical tasks is always a preferred alternative for IT pros. Besides other benefits, using Powershell takes us less time to complete the tasks. It is, of course, a professional way to accomplish almost any task in Windows Server operating systems.

Steps to Install and Configure DHCP Using PowerShell

Generally, the process of DHCP installation and configuration in Windows Server encompasses three tasks: installing the DHCP capability and its management tools, adding security groups, and authorizing DHCP in Active Directory. Let’s dive into the steps.

• Open the PowerShell from the Start Menu. See the picture below. You can also open it from Run usingpowershellcommand in the Run dialogue box.

• Before straightly going to the DHCP installation command, run theGet-WindowsFeaturecommand. This command lists all the features available in Windows Server 2022. It shows the name and installation state of those features. As the picture below shows, we have the DHCP feature available to install.

• To install DHCP and its management tools, run the commandInstall-WindowsFeature DHCP -IncludeManagementTools.Wait for a while till it finishes the installation, and you will see the details upon successful installation.

• Now, run thenetsh DHCP add SecurityGroupscommand to add the DHCP local security groups.

• The next step is to authorize the DHCP server to the Active Directory. To do so, use the command Add-DhcpServerInDC -DnsName ServerName.DomainName.Use your DHCP server name instead of the ServerName and your domain name instead of the DomainName in the above command. In my case, technigDC is the DHCP server name, and Technig.com is the domain name, as shown in the below picture.

• At this point, we are all done with our DHCP installation and configuration. We can view the authorized DHCP servers in Active Directory usingGet-DhcpServerInDCcommand.

That is all with DHCP installation and configuration using Windows PowerShell. That simple, it is installed and authorized.

Summary

Using Windows PowerShell is a professional way of completing configuration tasks on Windows OSs, including Windows Server 2022. Throughout this article, we explained how we can install and configure DHCP on Windows Server 2022 using the PowerShell tool. We saw that we can easily do it using a few simple command lines.

In the end, I hope you found this article helpful. Feel free to put your related questions in the comment section below.

Dynamic Host Configuration Protocol (DHCP) is a handy protocol that automatically assigns IP addresses to clients in a network. It is one of the most popular and most used protocols in networking. DHCP plays a vitally important role in almost any enterprise of any size. We make use of this protocol in any network environment where we are dealing with assigning IP addresses to devices. As an example, it is present in a home router as well as in a large enterprise with thousands of devices connected to the network. One of the basic and fundamental topics regarding DHCP is its installation and configuration in an environment. And that is what this article covers in detail. Since Windows Server 2022 is the latest and most powerful Server OS, this article covers how to install and configure DHCP in Windows Server 2022 using Server Manager.

Installing DHCP Using Server Manager

Using Server Manager is an easy and user-friendly method to install DHCP on Windows Server 2022. This article explains the process in a step-by-step approach.

• Open Server Manager from the Start Menu.

• On the Server Manager console, click on Manage and choose Add Roles and Features. Then on the first wizard, click on Next.

• On the Installation Type, check out the first option as shown in the below picture, and then click on Next.

• Choose the server on which you want to install DHCP from the Server Pool section, and click on Next.

• Click on DHCP Server from the Roles list. Click on Add Features on the new window that pops up. Finally, click on Next.

• Just click on the Next button on both the Features and DHCP Server sections.
• On the Confirmation window, check out the Restart the destination server automatically if required and click on Install, afterwards. Wait a while until the DHCP role installation completes.

Once the last step gets completed, we are all done with the DHCP installation. However, we still need to perform the DHCP post-installation configurations like adding security groups and authorizing DHCP to the Active Directory Domain Services.

DHCP Post-Installation Configurations on Windows Server 2022

DHCP post-installation configuration on Windows Server 2022 is a brief and simple process. Particularly, we do two things: the first is adding DHCP security groups, and the second is DHCP authorization. They are, in fact, in continue to the DHCP installation. The followings are the steps.

• Right after the DHCP installation completes, we will see the blued Complete DHCP configuration text. See the picture below. This linked text takes us to the post-configuration wizard. We can close this window and still go to the post-configuration using the notification flag on the Server Manager. Both take us to the same window.

• Read the description on the first section of the DHCP post-installation wizard, and click on Next.

• In the Authorization section, specify your credentials to authorize DHCP in active directory domain services. You can put it as default, or specify manually using Specify button at the second option. Once done, click on the Commit button.

• Click on the Close button in the Summary section when the DHCP authorization completes.

That is it! As easy as the above steps, we can install and configure DHCP in Windows Server 2022. First, we must add DHCP roles and features. The second step is to perform the post-installation configuration for DHCP capability.

This is the complete DHCP configuration guide on Windows server and Cisco router. The article is based on a step by step guide which helps you configure the DHCP server on Windows Server and Cisco routers easily.

Dynamic Host Configuration Protocol (DHCP) is a client/server protocol that automatically provides an Internet Protocol (IP) host with its IP address and other related configuration information such as the subnet mask and default gateway. RFCs 2131 and 2132 define DHCP as an Internet Engineering Task Force (IETF) standard based on Bootstrap Protocol (BOOTP), a protocol with which DHCP shares many implementation details. DHCP allows hosts to obtain required TCP/IP configuration information from a DHCP server.

Why we use DHCP in the network? Every device on a TCP/IP-based network must have a unique unicast IP address to access the network and its resources. Without DHCP, IP addresses for new computers or computers that are moved from one subnet to another must be configured manually; IP addresses for computers that are removed from the network must be manually reclaimed. With DHCP, this entire process is automated and managed centrally. The DHCP server maintains a pool of IP addresses and leases an address to any DHCP-enabled client when it starts up on the network. Because the IP addresses are dynamic (leased) rather than static (permanently assigned), addresses no longer in use are automatically returned to the pool for reallocation.

Benefits of DHCP Server.

Reliable IP address configuration. DHCP minimizes configuration errors caused by manual IP address configuration, such as typographical errors, or address conflicts caused by the assignment of an IP address to more than one computer at the same time.

Reduced network administration. DHCP includes the following features to reduce network administration:

• Centralized and automated TCP/IP configuration.
• The ability to define TCP/IP configurations from a central location.
• The ability to assign a full range of additional TCP/IP configuration values by means of DHCP options.
• The efficient handling of IP address changes for clients that must be updated frequently, such as those for portable computers that move to different locations on a wireless network.
• The forwarding of initial DHCP messages by using a DHCP relay agent, which eliminates the need for a DHCP server on every subnet.

• To Configure DHCP server on Windows Server 2016 follows the below step by step guide DHCP configuration video guide.

That’s all a system administrator needs to know about DHCP configuration on Cisco routers and Windows servers. For more information about the dynamic host configuration protocol read some book about DHCP and ask your question through the comment section.

The post DHCP Configuration Guide on Windows Server and Cisco Router appeared first on TECHNIG.

The step by step guide to install and configure DHCP Server in Windows Server 2012 R2. Dynamic Host Configuration Protocol (DHCP) is the core networking protocol to deploy Internet Protocol (IP) address automatically for network clients. In a small to medium and large networks, the IP address deployment has performed by DHCP Server. A DHCP Server assigns IP addresses to client computers and reduces IP management tasks.The DHCP protocol is available on most used Wireless Access point devices with preconfiguring of basic DHCP services for home users.

But in the enterprise network, DHCP Server require installation and configuration. In Microsoft Windows Server it a role base service. You must install it first and configure to work correctly. So I don’t take about DHCP Server on Cisco routers now because this article is about DCHP installation and configuration of Windows Server 2012 R2. 

 1. Install and Configure DHCP Server Role

To install DHCP Serve go to Dashboard on Server Manager and click Manage then click Add Rules and Features.

In the Role installation window select Role-based or feature-based installation the click Next.

Choose the server you want to install DHCP from the Server pool. Here we have one server and select by default.

From the Roles list select DHCP Server. When the Add Roles and Features Wizard Page opened, click Add Features then Click Next. That will install required features for DHCP Server.

In the Features window, do not change anything, just click Next.

Once read the information about DHCP Server and click Next button.

In the Confirm Installation page, select Restart the destination server automatically if required. Click Yes the warning window and click Install.

The installation will take a minute,when it has completed successfully click Complete DHCP Configuration link.

Read DHCP Post-Install configuration wizard description and click Next.

Set the appropriate user for management of DHCP Server. Here I leave it by default because the administrator (Shais) has the right privilege to perform DHCP Server configuration.

On the DHCP summary window clicks Close and close the DHCP Installation page also.

2. Configure DHCP Server and Create Scope

Now try to set up the installed DHCP server and create Scope to lease IP address for clients.

Type dhcpmgmt.msc in Windows Run and press enter to open DHCP management console.

On DHCP console window expends the domain name and IPv4.  Right, click the IPv4 the click New Scope.

Click Next on the New Scope Wizard page.

In the Scope, name defines the name of Scope and write any description then click Next.

Assign the start IP address range and the end IP address range. I have set from 192.168.100.1 to 192.168.100.254 which is a class C IP address. Leave the length 24 by default and click Next.

Add the exclusive range prevent them from leasing to the client by DHCP Server. The IP address range which reserved is use for Network Servers and popular workstation. Here I add 192.168.100.1 to 192.168.100.15.  Just set the IP address and click Add button then click Next.

Let the Lease Duration by default and click Next.

Only click Next the Configure DHCP Options, and Yes, I want to configure these options now must be checked.

If you have a router in your network, set the router IP address and click Add button, then click Next.

Type your domain name, and it’s IP address then click Next.

Do nothing for WINS Servers, because we don’t use WINS Server ether. Just click Next.

In Active Scope, windows click Next. Be sure the Yes, I want to active this scope now must check.

Finally, click Finish to close and finalize the installation of DHCP Server in Windows Server 2012 R2.

Now you can assign the IP address to your network clients automatically trough this DHCP Server.

How to Install DHCP Server on Windows Server 2016?

If you don’t like to read more details, just watch this simple lab manual to install and configure DHCP Server on your Windows Server.

Configure DHCP on Cisco Router. Last week we published a topic about installation and configuration of DHCP Server in Windows Server 2012 R2. We have introduced the DHCP Server “Install and Configure DHCP Server on Windows Server 2012 R2” and told the necessary services and network protocols requirement if you don’t know the basic of DHCP Server? you must read the article first.

Create and Configure a CCNA Lab within Cisco Packet Tracer.

Download the DHCP configuration in Cisco router lab of packet tracer from the end of this post or try to create your own network lab with two routers and their LAN networks and then configure it with the following step by step guide.

Configure the Router 1 with below IP address and initial configuration. I assume you know and understand the basic router and Switch configuration clearly. So no need to explain the functions of the basic router and switch commands line.

Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.

Router(config)#hostname R1
R1(config)#interface serial 0/0/0
R1(config-if)#ip address 10.10.10.1 255.255.255.252
R1(config-if)#no shutdown

R1(config-if)#clock rate 64000
R1(config-if)#

For Router 2, configure the same interface serial 0/0/0 and FastEthernet 0/0 with the following commands.

Router>enable
Router#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
Router(config)#hostname R2
R2(config)#interface serial 0/0/0
R2(config-if)#ip address 10.10.10.2 255.255.255.252
R2(config-if)#no shutdown

R2(config-if)#

R2(config)#interface fastEthernet 0/0
R2(config-if)#ip address 192.168.10.1 255.255.255.0
R2(config-if)#no shutdown

Configure DHCP on Cisco Router Using Packet Tracer

Let’s configure Router 2 as DHCP Server and set the clients to get their IP address from DHCP Server in Cisco Router.

In the R2 while you are in the config mode, type the command ‘IP DHCP excluded-address 192.168.10.1 192.168.10.20‘ and then press enter. This command ‘ip dhcp excluded-address’ will create an exclusive range of IP addresses which reserved for Network Servers and DHCP Server will not assign them to clients.

The ‘ip dhcp pool‘ command creates a pool for a network. You can create many pools on a router for all Local area network that connected to the router.

R2>enable
R2#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R2(config)#ip dhcp excluded-address 192.168.10.1 192.168.10.20
R2(config)#ip dhcp pool Technig_Clients
R2(dhcp-config)#
R2(dhcp-config)#network 192.168.10.0 255.255.255.0
R2(dhcp-config)#default-router 192.168.10.1
R2(dhcp-config)#dns-server 192.168.10.100
R2(dhcp-config)#

Now go to client setting and set the IP Configuration to DHCP and see the client get a new IP address from DHCP Server.

So that’s it, configure DHCP on Cisco router within a minute! Simple and easy.

DHCP Relay on Cisco Router

Remember some DHCP options (DHCP Relay Agent) when you need to provide IP addresses from a DCHP server to clients that are outside of your network or are not in the same Local Area Network. You must use the ‘ip helper-address‘ to forward the DHCP client requests to the remote host.

Configure the R1 to relay the DHCP client request. It does not work without routing. So configure Routers with static or dynamic routing. Here I’m testing with RIP.

R1>enable
R1#configure terminal
Enter configuration commands, one per line. End with CNTL/Z.
R1(config)#interface fastEthernet 0/0
R1(config-if)#ip helper-address 10.10.10.2
R1(config-if)#exit

R1(config)#router rip
R1(config-router)#network 10.10.10.0
R1(config-router)#network 192.168.30.0
R1(config-router)#exit

Go to the client IP configuration setting and see the forwarded request by DHCP Server.

Hope you learn the configuration of the DHCP Server on the Cisco Router and Download the DHCP on Cisco Router Packet Tracer.

This article “configure DHCP failover on Windows Server” is apply-able on Windows server 2012 and higher for DHCP High Availability. The DHCP server failover feature provides the ability to have two DHCP servers provide IP addresses and option configuration to the same subnet or scope, providing for continuous availability of DHCP service to clients. The two DHCP servers replicate lease information between them, allowing one server to assume responsibility for servicing of clients for the entire subnet when the other server is unavailable. It is also possible to configure failover in a load-balancing configuration with client requests distributed between the two servers in a failover relationship.

The DHCP failover in Windows Server enables administrators to deploy a highly resilient DHCP service to support a large enterprise without the challenges of the options discussed earlier. The main goals of the feature are the following:

• Provide DHCP service availability at all times on the enterprise network.
• If a DHCP server is no longer reachable, the DHCP client is able to extend the lease on its current IP address by contacting another DHCP server on the enterprise network.

Read the Understand and Deploy DHCP Failover article on Microsoft technet.

Configure DHCP Failover on Windows Server?

You need to have two DHCP servers to configure DHCP failover on Windows Server. Install DHCP on both servers and don’t create scope on the second one. Just create a scope on the primary DHCP server.

1. On Windows server type “dhcpmgmt.msc” on Run and press enter to open DHCP Manager.
2. On the DHCP console right click the DHCP and click Add Server. Select the second DHCP server and add it to current DHCP console.

3. To configure DHCP Failover on Windows Server, right click on IPv4 of primary DHCP and select Configure Failover. On the welcome page of Configure Failover select Select all and click Next.

4. Add the second DHCP server and click Next.

5. On the Create a new failover relationship page, select Load balance mode and type a password then click Next.

6. Finally click Finish to set up failover between two servers. Make sure the process should be finished successfully. Close the page and to to see the changes on DHCP management console.

7. Once refresh the DHCP console or reconnect the server to see the final result. Now the DHCP servers are ready to work as DHCP load balancing service and your clients never fail to obtain IP address.

That is all about DHCP High Available or configure DHCP Failover on Windows Server 2016. The same configuration works on Windows Server 2012 also.

The post How to Configure DHCP Failover on Windows Server 2016? appeared first on TECHNIG.

Dynamic host configuration protocol (DHCP) is providing IP addresses to network client workstations and server machines. The DHCP High Available role acts as load sharing and fault tolerance. So in this article we explain and configure DHCP high available to an step by step manner guide.

Before applying DCHP high available role in your production environment, once test it in a testing lab. For configuring dhcp high availability you need two Windows Server and a client for testing. I have a DC server installed Active directory, DNS Server, and DHCP Server. My second server is only DHCP installed.

The DHCP Failover Architecture

The two features of DHCP role for high availability are Hot Standby, and Load Sharing. In hot standby mode the primary server is responsible for providing IP addresses to clients and the secondary server is watching the primary server failure . When the primary DHCP server failed or not servicing properly, the secondary server start works to provide IP address instead of primary server.

If you are new with DHCP server, I recommend you to read the following article about DHCP Server.

1. Install and configure DHCP role in Windows Server 2012 R2
2. How to Configure DHCP in Cisco Routers?

I assume you know the basics of Dynamic Host Configuration Protocol.

Configure DHCP High Available

Now let’s start to configure DHCP high available in Windows Server 2012 R2 or Windows Server 2016. Both works the same.

1. Login to DC server and type “dhcpmgmt.msc” in Windows run to open the DHCP management console.

2. Add the second DHCP server to this primary DHCP management console. In order to do this right click the DHCP and select Add Server. Now select the secondary DHCP server from the list or browse and type the name of server you want to add it. Then click OK to add the second server.

Here is the result, the two servers are now have a Central access.

3. To configure DHCP high available, right click on IPv4 on primary server and click Configure Failover. On the Configure Failover page read the introduction to DCHP failover then click Next.

4. Click Add Server and select the server form list. or simply specify the partner server to use for failover then click Next.

5. On the Create a new failover relationship page, select Load balance mode and type a password then click Next.

6. Finally click Finish to set up failover between two servers. Make sure the process should be finished successfully. Close the page and to to see the changes on DHCP management console.

7. Once refresh the DHCP console or reconnect the server to see the final result. Now the DHCP servers are ready to work as DHCP load balancing service and your clients never fail to obtain IP address.

It is the easiest way using DHP high availability in Windows Servers 2012 and Windows Server 2016. I hope it has been informative for you and appreciate you to comment us the DHCP relevant problems.
