Event-triggered Updates

The server can notify online agents to update components after it downloads the latest components, and offline agents when they restart and then connect to the server. Optionally initiate Scan Now (manual scan) on OfficeScan agent computers after the update.

Description

Initiate component update on agents immediately after the OfficeScan server downloads a new component

The server notifies agents to update as soon as it completes an update. Frequently updated agents only need to download incremental patterns, thus reducing the time it takes to complete the update (see OfficeScan Server Component Duplication for details about incremental patterns). However, updating frequently may adversely affect the server’s performance, especially if you have a large number of agents updating at the same time.

If you have agents on roaming mode and you want these agents to update as well, select Include roaming and offline agent(s). See OfficeScan Agent Roaming Privilege for details about roaming mode.

Let agents initiate component update after restarting and connecting to the OfficeScan server (roaming agents excluded)

Any agent that missed an update immediately downloads components when it establishes connection with the server. The agent may miss an update if it is offline or if the endpoint where it is installed is not up and running.

Perform Scan Now after update (roaming agents excluded)

The server notifies agents to scan after an event-triggered update. Consider enabling this option if a particular update is a response to a security risk that has already spread within the network.

Note:

If the OfficeScan server is unable to successfully send an update notification to agents after it downloads components, it automatically resends the notification after 15 minutes. The server continues to send update notifications up to a maximum of five times until the agent responds. If the fifth attempt is unsuccessful, the server stops sending notifications. If you select the option to update components when agents restart and then connect to the server, component update will still proceed.
