One of the first steps after installing the DHCP role on Windows Server 2016 (or older versions) is to authorise the server in the Active Directory infrastructure.
This is required so that the DHCP Server may assign IP addresses to Active Directory clients. Otherwise, if a DHCP Server is not authorised, IP address distribution will be halted.
You must use a user account that is a member of the Enterprise Admins security group or an account with delegated rights for that domain to authorise or unauthorize a DHCP Server.
Authorize DHCP Server using the GUI
In an open DHCP administration console, right-click the server name and then select Authorize.
Open the DHCP snap-in.
In the left pane, right-click on DHCP and select New Server.
Type in the name of the new DHCP server and click OK.
Click on the server entry in the left pane.
Right-click on the server and select Authorize.
Wait a few seconds, and after refreshing the list, you’ll notice a green indicator in each scope indicating that the DHCP Server is now authorised.
To unauthorize a DHCP server, right-click on it and then select Unauthorize.
Authorize DHCP Server using PowerShell
To start, run the following command to get a list of all authorised DHCP Servers in Active Directory.
Get-DhcpServerInDC
Use the command below to authorise a DHCP server, replacing the necessary parameters with your own.
Add-DhcpServerInDC -DnsName "dhcp01.windowstechno.local" -IPAddress 10.3.20.10
Use the command below to unauthorize a DHCP server, replacing the necessary parameters with your own.
Remove-DhcpServerInDC -DnsName "dhcp01.windowstechno.local"-IPAddress 10.3.20.10
