Trend Micro OfficeScan 10 Service Pack 1 Administrator’s Guide
Update Overview
4-10
All component updates originate from the Trend Micro ActiveUpdate server. When
updates are available, the OfficeScan server and Smart Scan Server (local or global) download
the updated components. There are no component download overlaps between the two
servers because each one downloads a specific set of components.
Note: You can configure both the OfficeScan server and Smart Scan Server to update from
a source other than the Trend Micro ActiveUpdate server. To do this, you need to set
up a custom update source. If you need assistance setting up this update source,
contact your support provider.
OfficeScan Server and Client Update
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 a
Smart Scan Server.
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 when to use them:

Clients
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.
