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 for steps to configure the list.
After you have set up and saved the list, the update process proceeds as follows:
The Update Agent updates from the first entry on the list.
If unable to update from the first entry, the agent updates from the second entry, and so on.
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.
If unable to update from all possible sources, the Update Agent quits the update process.
The update process is different if the option Update agent: always update from standard update source (OfficeScan server) is enabled and the OfficeScan server notifies the agent to update components. The process is as follows:
The agent updates directly from the OfficeScan server and disregards the update source list.
If unable to update from the server, the agent 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 the first entry in the Customized Update Source List.
Place the ActiveUpdate server at the top of the list only if you experience problems updating from the OfficeScan server. When clients update directly from the ActiveUpdate server, significant bandwidth is consumed between the network and the Internet.
If unable to update from all possible sources, the Update Agent quits the update process.
