I have a printer device that needs IP 192.168.1.107. somehow, while this printer was turned off, this address was accidentally taken by a DHCP laptop client in another building here on our network. I want to "rip" away the address from this laptop client (forcing it to take a new, different address) and then give the .107 IP back to the printer device. When I try to do this, however, in DHCP Server, the laptop keeps "winning". I tried deleting the DHCP lease and DNS entries - created a reservation for 192.168.1.107 so that it was no longer valid in the DHCP scope - and restarting the printer to renew its IP connection. but nothing seems to work. the laptop continues to retain the IP. is there a way to do this, without needing to get access to the laptop?
