Customized Update Sources for Update Agents Parent topic

Aside from the OfficeScan server, Update Agents can update from custom update sources. Custom update sources help reduce client update traffic directed to the OfficeScan server. Specify the custom update sources on the Customized Update Source List, which can accommodate up to 1024 update sources. See Customized Update Sources for OfficeScan Clients for steps to configure the list.
Note
Note
Ensure that the Update Agents update components, domain settings, and client programs and hot fixes, only from the OfficeScan server option is disabled on the
Update Source (Networked Computers) screen (Updates → Networked Computers → Update Source) in order for Update Agents to connect to the customized update sources.
After you have set up and saved the list, the update process proceeds as follows:
  1. The Update Agent updates from the first entry on the list.
  2. If unable to update from the first entry, the agent updates from the second entry, and so on.
  3. If unable to update from all entries, the agent checks the following options:
    • Update components from the OfficeScan server if all customized sources are not available or not found: If enabled, the agent updates from the OfficeScan server.
      If the option is disabled, the agent then tries connecting directly to the Trend Micro ActiveUpdate server if any of the following are true:
      Note
      Note
      You can only update components from the Active Update server. Domain settings, programs and hot fixes can only be downloaded from the server or Update Agents.
      • In Networked Computers → Client Management, click Settings → Privileges and Other Settings → Other Settings → Update Settings, the option Clients download updates from the Trend Micro ActiveUpdate Server is enabled.
      • The ActiveUpdate server is not included in the Customized Update Source List.
    • Update domain settings from the OfficeScan server if all customized sources are not available or not found: If enabled, the agent updates from the OfficeScan server.
    • Update client programs and hot fixes from the OfficeScan server if all customized sources are not available or not found: If enabled, the agent updates from the OfficeScan server.
  4. If unable to update from all possible sources, the Update Agent quits the update process.
The update process is different if the option Update agent: always update from standard update source (OfficeScan server) is enabled and the OfficeScan server notifies the agent to update components. The process is as follows:
  1. The agent updates directly from the OfficeScan server and disregards the update source list.
  2. If unable to update from the server, the agent tries connecting directly to the Trend Micro ActiveUpdate server if any of the following are true:
    • In Networked Computers → Client Management, click Settings → Privileges and Other Settings → Other Settings → Update Settings, the option Clients download updates from the Trend Micro ActiveUpdate Server is enabled.
    • The ActiveUpdate server is the first entry in the Customized Update Source List.
    Tip
    Tip
    Place the ActiveUpdate server at the top of the list only if you experience problems updating from the OfficeScan server. When OfficeScan clients update directly from the ActiveUpdate server, significant bandwidth is consumed between the network and the Internet.
  3. If unable to update from all possible sources, the Update Agent quits the update process.
