A laptop is connected to the Internet from a non-corporate connection. The Symantec Network Access Control client is in the Remote location defined by an administrator. The client has no access to corporate network resources. The Symantec Network Access Control client reports that Host Integrity has failed due to out-of-date virus definitions for a third-party antivirus. The user is unable to access the corporate remediation servers to remediate this definition issue. How can a Symantec Network Access Control administrator avoid this situation in the future?
