Note

La plateforme De protection d’accès réseau n’est pas disponible à partir de Windows 10

 

Configure un module de validateur d’intégrité système (SHV), y compris l’inscription et l’annulation de l’inscription auprès du système NAP.

Note

Le SDK NAP contient également un ensemble complet d’exemples de code qui se trouvent dans ...\Samples\NetDS\NAP... répertoire de votre installation du Kit de développement logiciel (SDK). Cet exemple de jeu inclut un agent d’intégrité système (SHA), SHV et un client d’application (EC). Il propose des scénarios NAP complets qui configurent la communication entre SHA-SHV et SHA-EC.
