Standard Update Source for Update Agents
Keeping Protection Up-to-Date
The OfficeScan server is the standard update source for Update Agents. If you
configure agents to update directly from the OfficeScan server, the update process
proceeds as follows:
1. The Update Agent obtains updates from the OfficeScan server.
2. If unable to update from the OfficeScan server, the agent tries connecting directly
to the Trend Micro ActiveUpdate server if any of the following are true:
• In Networked Computers > Client Management > Settings > Privileges
and Other Settings > Other Settings tab > 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: Place the ActiveUpdate server at the top of the list only if you experience
problems updating from the OfficeScan server. When Update Agents 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.
Customized Update Sources for Update Agents
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 on page 5-28 for steps to configure the list.
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.
