Abstract: A system and method for generating and tracking health diagnoses of devices connected to a computer network via a statement of health provided by each device. The system monitors the health of devices on the network and attempts to engage the operator of undiagnosed devices in order to provide a diagnosis. Undiagnosed devices are quarantined to restrict their access to network resources. For example, access requests from quarantined devices to certain Web services may be intercepted and the device redirected to a page informing the operator of the need to provide a health diagnosis by installing or activating a compatible system health agent.
