you need to enable filter lists first ... so i guess the command we need to look for is something like: Set-DhcpServerv4FilterList -ComputerName "dhcpserver.contoso.com" -Allow $True This would enabled the allow list ... wich allready cotains mac addresses so you don't need to add entrys with: Add-DhcpServerv4Filter -List Allow -MacAddress "F0-DE-F1-7A-00-5E" -Description "Laptop 09" So "Add-DhcpServerv4Filter" answers should be wrong https://docs.microsoft.com/en-us/powershell/module/dhcpserver/add-dhcpserverv4filter?view=win10-ps https://docs.microsoft.com/en-us/powershell/module/dhcpserver/set-dhcpserverv4filterlist?view=win10-ps

I think B is correct. Since -MacAddress parameter on Add-DHCPServerv4Filter can't use wildcard. When you run the cmdlet for each MacAddress, you can solve problem.

Enable filter lists on the DHCP server service: C:\> Set-DhcpServerv4FilterList -ComputerName "dhcpserver.contoso.com" -Allow $True -Deny $True https://docs.microsoft.com/en-us/powershell/module/dhcpserver/set-dhcpserverv4filterlist?view=win10-ps

Correct. You need to enable the list first - done in lab and confirmed.
