I need to create a GPO to grant users in the local Guests group access to the Personal Certificate Store. The reason I want to do this is because we run Cisco Secure Endpoint on our machines, and when a member of the local Guests group logs in, the Cisco Secure Endpoint cannot connect to the server. When we log in as another user that is not in the Guests group, the Cisco software works fine. I reached this conclusion based on the Event Viewer logs that had errors about the certificate store not being available.
