Event ID 1020 — WSHA Client Remediation

  • Article

Applies To: Windows Server 2008

Remediation refers to the act or process of correcting a client configuration or software state that is not compliant with network health requirements. If Network Access Protection (NAP) policies are configured for automatic remediation, the Windows Security Health Agent (WSHA) will attempt to modify the client configuration to bring it into compliance with network health requirements.

For the WSHA, remediation of a client computer configuration depends on health requirements specified by the Windows Security Health Validator (WSHV) and the access of client computers to resources required to update and maintain their configuration to meet requirements of the WSHV.
