Applies To: Windows Server 2008, Windows Server 2008 R2, Windows Server 2012

  • Be issued by a certification authority (CA) that is trusted by client computers. A CA is trusted when its certificate exists in the Trusted Root Certification Authorities certificate store for the current user and local computer.

The following objectives assist in managing NPS server certificates in deployments where the trusted root CA is a third-party CA, such as Verisign, or is a CA that you have deployed for your public key infrastructure (PKI) by using Active Directory Certificate Services (AD CS) in Windows Server 2008.

The following objectives are part of managing NPS server certificates:
