In a Network Access Protection (NAP) deployment, this problem typically occurs when you start the NAP Agent service on a server computer.

Description of system behavior

If you start the NAP Agent service on a computer running Windows Server 2008 R2 or Windows Server® 2008, it will display an error event indicating that a system health agent (SHA) is not present. This is because the Windows System Health Agent (WSHA) is not installed on Windows Server 2008 R2 or Windows Server 2008.

Associated operating system events

  • NAP client event ID 13: The Network Access Protection Agent failed to the peripheral component %1. The error code was %2. See the administrator for more information.

Root cause diagnosis and resolution

If this event occurs on a computer running Windows Server 2008 R2 or Windows Server 2008, no action is required.
