I recently had to replace the DHCP service at one of my customers. The customer was still using a solution implemented on a old firewall. Enclosed is the initial situation (see screen below).

# Installing the server role
Install-WindowsFeature DHCP -IncludeManagementTools

# Create DHCP security groups for authorization
Netsh DHCP Add SecurityGroups

# DHCP - Server Restart
Restart-Service DHCPServer

# Authorize DHCP server
Add-DHCPServerInDC

# Showing available Net-Adapter
Get-NetAdapter

# DHCP Netadapter - Binding
Set-DHCPServerv4Binding -BindingState $True -InterfaceAlias "Ethernet"

# Creating a DHCP range
Add-DhcpServerv4Scope -Name <Name> -StartRange <IP> -EndRange <IP> -SubnetMask <SubnetMask>

# Disable Scope
Set-DHCPServerv4Scope -ScopeId <IP> -state Inactive

# Enabling Continuous Dynamic DNS Updates
Set-DhcpServerv4DnsSetting -ComputerName "<Name>" -DynamicUpdates
"Always" -DeleteDnsRRonLeaseExpiry $True

Set-DHCPServerv4OptionValue -OptionID 3 -Value <IP> -ScopeID <IP> -ComputerName <FQDN>

Set-DhcpServerv4OptionValue -DnsDomain <Domain> -DnsServer <IP>

# DHCP-Server Config Backup
Backup-DHCPServer -path C:\BackupDHCP

# Restore DHCP-Server Config Backup
Restore-DHCPServer -ComputerName <Name> -Path C:\BackupDHCP

# DHCP - Server Restart
Restart-Service DHCPServer
