A noncompliant NAP client on the restricted network can access remediation servers and install the necessary components and updates. After remediation is complete, the NAP client can perform a new health evaluation in conjunction with a new request for network access or communication.

The NAP health policy server can use a health requirement server to validate the health state of the NAP client or to determine the current version of software or updates that need to be installed on the NAP client. For example, a health requirement server might track the latest version of an

When a NAP-capable client computer contacts a NAP enforcement point, it submits its current health state. The NAP enforcement point sends the NAP client's health state to the NAP health policy server for evaluation using the
