Certificate Acquistion and Deletion

  • Article

Applies To: Windows Server 2008 R2

If a NAP client computer is not able to contact the HRA server, or if server components are not correctly configured on HRA servers, certification authority (CA) servers, or Network Policy Server (NPS), the client computer will not be able to obtain a health certificate. IPsec policies typically restrict network communication of computers that do not have a valid health certificate.

A compliant NAP client computer might not be able to obtain a health certificate from an HRA server for the following reasons:

  • An error in trusted server group configuration of the NAP client
  • Network connectivity problems on the HRA server, the CA server, or the NAP client
  • A configuration problem on the HRA server
  • A configuration problem on the CA server associated with the HRA
