OfficeScan Server and OfficeScan Client Update Parent topic

The OfficeScan server downloads most of the components that clients need. The only component it does not download is the Smart Scan Pattern, which is downloaded by smart protection sources.
If an OfficeScan server manages a large number of clients, updating may utilize a significant amount of server computer resources, affecting the server’s stability and performance. To address this issue, OfficeScan has an Update Agent feature that allows certain clients to share the task of distributing updates to other clients.
The following table describes the different component update options for the OfficeScan server and clients, and recommendations on when to use them:

Server-Client Update Options

Update Option
Description
Recommendation
ActiveUpdate server → Server → Client
The OfficeScan server receives updated components from the Trend Micro ActiveUpdate server (or other update source) and initiates component update on clients.
Use this method if there are no low-bandwidth sections between the OfficeScan server and clients.
ActiveUpdate server → Server → Update Agents → Client
The OfficeScan server receives updated components from the ActiveUpdate server (or other update source) and initiates component update on clients. Clients acting as Update Agents then notify clients to update components.
If there are low-bandwidth sections between the OfficeScan server and clients, use this method to balance the traffic load on the network.
ActiveUpdate server → Update Agents → Client
Update Agents receive updated components directly from the ActiveUpdate server (or other update source) and notifies clients to update components.
Use this method only if you experience problems updating Update Agents from the OfficeScan server or from other Update Agents.
Under most circumstances, Update Agents receive updates faster from the OfficeScan server or from other Update Agents than from an external update source.
ActiveUpdate server → Client
OfficeScan clients receive updated components directly from the ActiveUpdate server (or other update source).
Use this method only if you experience problems updating clients from the OfficeScan server or from Update Agents.
Under most circumstances, clients receive updates faster from the OfficeScan server or from Update Agents than from an external update source.
