Customized Update Sources for OfficeScan Agents
Aside from the OfficeScan server, OfficeScan agents can update from custom update sources. Custom update sources help reduce OfficeScan agent update traffic directed to the OfficeScan server and allow OfficeScan agents that cannot connect to the OfficeScan server to get timely updates. Specify the custom update sources on the Customized Update Source List, which can accommodate up to 1024 update sources.
Trend Micro recommends assigning some OfficeScan agents as Update Agents and then adding them to the list.
