Certificates and the agent

The Verisign Root Certificate Authority (CA) must be current. This is required because the agent software is signed using a Verisign certificate. If your certificate is not current, you must download the Root CA certificate and install it to the Local Computer\Trusted Root Certification Authority store on the server hosting the agent.
