Using WMI and Powershell we can remotely configure a client machine to use DHCP as long as you (1) have administrator rights on the remote machine (2) want all interfaces to be DHCP (3) know the computer name or IP of the remote machine (4) have Powershell installed on your machine, remote machine is not required.
