Configure the OfficeScan server to download components from the Trend Micro ActiveUpdate server or from another source. You may specify another source if the OfficeScan server is unable to reach the ActiveUpdate server directly. For a sample scenario, see Isolated OfficeScan Server Updates.
After the server downloads any available updates, it can automatically notify agents to update their components based on the settings you specified in Updates > Agents > Automatic Update. If the component update is critical, let the server notify the agents at once by going to Updates > Agents > Manual Update.
If you do not specify a deployment schedule or event-triggered update settings in Updates > Agents > Automatic Update, the server will download the updates but will not notify agents to update.
