Configuring OfficeScan Agent Automatic Updates

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

  • Include Independent and offline agent(s)

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

• Perform Scan Now after update (Independent agents excluded)

For details about the available options, see Event-triggered Updates.

• Minute(s) or Hour(s)

  The option to Update agent configurations only once per day is available when scheduling an hourly or minute-based update frequency. The configuration file contains all OfficeScan agent settings configured using the web console.

  Tip:

  Trend Micro often updates components; however, OfficeScan configuration settings probably change less frequently. Updating the configuration files with the components requires more bandwidth and increases the time OfficeScan needs to complete the update. For this reason, Trend Micro recommends updating OfficeScan agent configurations only once per day.

• Daily or Weekly

  Specify the time of the update and the time period the OfficeScan server notifies agents to update components.

  Tip:

  This setting prevents all online agents from simultaneously connecting to the server at the specified start time, significantly reducing the amount of traffic directed to the server. For example, if the start time is 12pm and the time period is 2 hours, OfficeScan randomly notifies all online agents to update components from 12pm until 2pm.

OfficeScan cannot notify offline agents immediately. Select Let agents initiate component update after restarting and connecting to the OfficeScan server (Independent agents excluded) to update offline agents that become online after the time period expires. Offline agents without this setting enabled update components on the next schedule or during a manual update.
