Customized Update Source

Aside from the OfficeScan server, clients can update from custom update sources. Custom update sources help reduce client update traffic directed to the OfficeScan server and allows clients that cannot connect to the OfficeScan server to get timely updates. Specify the custom update sources on the Customized Update Source List, which can accommodate up to 1024 update sources.

Trend Micro recommends assigning some clients as Update Agents and then adding them to the list.

To configure the customized update source list: >>>

Updates > Networked Computers > Update Source

Select Customized Update Source and click Add.
In the screen that displays, type a range of client IP addresses that will receive updates from an update source.
Specify the update source. You can select an Update Agent if one has been assigned or type the URL of a specific source.
Click Save.
Edit an update source by clicking the IP range link. Modify the settings in the screen that displays and click Save.
Remove an update source from the list by selecting the check box and clicking Delete.
To move an update source, click the up or down arrow. You can only move one source at a time.

After you have set up and saved the list, the update process proceeds as follows:

A client updates from the first entry on the list.
If unable to update from the first entry, the client updates from the second entry, and so on.
If unable to update from all entries, the client checks the following options:

Update components from the OfficeScan server if all customized sources are unavailable or not found: If enabled, the client updates from the OfficeScan server.

If the option is disabled, the client then tries connecting directly to the Trend Micro ActiveUpdate server if any of the following are true:

You can only update components from the Active Update server. Domain settings, programs and hot fixes can only be downloaded from the server or Update Agents.
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://osce105-p.activeupdate.trendmicro.com/activeupdate) is not included in the Customized Update Source List.
Update domain settings from the OfficeScan server if all customized sources are unavailable or not found: If enabled, the client updates from the OfficeScan server.
Update client programs and hot fixes from the OfficeScan server if all customized sources are unavailable or not found: If enabled, the client updates from the OfficeScan server.

If unable to update from all possible sources, the client quits the update process.
