Is your DHCP also going to be provisioning the gateway address? If it is you'll need to do two things:

 Set-NetIPInterface -InterfaceAlias 'Ethernet 1' -Dhcp Enabled

and:

 Get-NetIPAddress -InterfaceAlias 'Ethernet 1' | Remove-NetRoute

Also, knowing just the name of the machine isn't enough. You'll also have to provide the name of the NIC you want to change, and that may be different on each machine.

When you change the IP address you're going to be disconnected, so build that problem into the script you write.

Hi,

Have a look at this page which has details of the add-dhcpserverv4reservation command, which includes some sample scripts on how to import from a file.
