This section describes and provides solutions for problems that can occur with Network Access Protection (NAP) system health agents (SHAs).
On client computers, SHAs perform system health updates and publish their status in the form of statements of health (SoHs) to the NAP Agent service. An SoH contains information that NAP health policy servers can use to verify the health state of the client computer. For example, an SoH might contain information that Windows Firewall is turned off. Each SHA is matched to a system health validator (SHV) on the server side of the NAP platform architecture. The corresponding SHV returns a statement of health response (SoHR) to the client, informing it of what to do if the SHA is not in a required state of health.
The following is a list of known problems and solutions associated with SHAs in a NAP deployment. Problems and solutions that might be inter-related are noted and linked if needed. Problems that have more than one possible root cause are noted and have more than one proposed solution. Choose the problem that best describes your situation, and then complete the procedures for the suggested fix. This list will be continuously updated as new problems and solutions are found.
