From Wild Paw:
Keep your network and physical and virtual computers safe from malware, recently terminated employees, or attack by remotely disabling a host's network cards. NIC Padlock allows an administrator to temporarily or permanently disable a remote host's network interface cards (NIC's). NIC Padlock is a great solution when you need to ensure that a real or virtual remote host is disconnected from your network immediately.
