Abstract
The present invention includes a method and apparatus for controlling data link layer access to protected servers on a computer network by a client device. Address resolution requests broadcast on the network by the client device seeking access to any network device are received and then processed to determine whether the client device is unknown. If the client device is unknown, restriction address resolution replies are transmitted to the protected devices to restrict access by the client device to the protected devices and allow access to an authentication server. The authentication server is monitored to determine if the client device is authorized or unauthorized by the authentication server. If the client device is authorized, access is allowed to the protected devices. If the client device is unauthorized, blocking address resolution replies are transmitted on the computer network to block access by the client device to all other network devices.
