Problème avec le certificat SSL CA

Bonjour,

Sur certianes machines Windows 2008 R2 l'agent me renvoie cette erreur. Quelle en peut être l'origine ?

"Starting OCS Inventory NG Agent on Wednesday, February 24, 2016 14:08:22.
AGENT => Running OCS Inventory NG Agent Version 2.0.5.0
AGENT => Using OCS Inventory NG FrameWork Version 2.0.5.0

Merci
