Update Source for Update Agents
Update Agents can obtain updates from various sources, such as the OfficeScan server 
or a customized update source. Configure the update source from the Web console’s 
Update Source screen.
To configure the update source for the Update Agent:
PATH: UPDATES > NETWORKED COMPUTERS > UPDATE SOURCE
1. Select whether to update from the update agent standard update source (OfficeScan 
server) or update agent customized update source.
2. Click Notify All Clients.
Update Agent Customized Update Source
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 
Source on page 4-25 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.
3. If unable to update from all entries, the agent checks if the option Update from 
OfficeScan server if all customized sources are not available or not found is 
enabled. 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 is 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 
(http://osce10-p.activeupdate.trendmicro.com/activeupdate) is not included in 
the Customized Update Source List.
