We need DHCP PowerShell cmdlet to be available in order to manage DHCP. By default, the DHCP module is not loaded in PowerShell. We need to install and the import the DHCP module before we can use it.
Importing DHCP Powershell cmdlet
If you’re going to use PowerShell on the DHCP server, then ensure the Management tools are also installed. Below is the PowerShell command to install DHCP role with management tools
Add-WindowsFeature -Name DHCP –IncludeManagementTools
If you’re going to manage the server remotely, then you can install RSAT tool – features
Add-WindowsFeature RSAT-DHCP
Once installed, import the DHCP module before you can use.
