The OfficeScan server is the standard update source for clients.
If the OfficeScan server is unreachable, clients will not have a backup source and will therefore remain outdated. To update clients that cannot reach the OfficeScan server, Trend Micro recommends using Client Packager. Use this tool to create a package with the latest components available on the server and then run the package on clients.
The client’s IP address (IPv4 or IPv6) determines if connection to the OfficeScan server can be established. For details about IPv6 support for client updates, see OfficeScan Client Update Sources.
To configure the standard update source for clients:
Updates > Networked Computers > Update Source
Select Standard update source (update from OfficeScan server).
Click Notify All Clients.
This topic discusses the update process for clients. The update process for Update Agents is discussed in another topic. For details, see Standard Update Source for Update Agents.
If you configure clients to update directly from the OfficeScan server, the update process proceeds as follows:
The client obtains updates from the OfficeScan server.
If unable to update from the OfficeScan server, the client tries connecting directly to the Trend Micro ActiveUpdate server if the option Clients download updates from the Trend Micro ActiveUpdate Server is enabled in Networked Computers > Client Management > Settings > Privileges and Other Settings > Other Settings tab > Update Settings.
Only components can be updated from the ActiveUpdate server. Domain settings, programs and hot fixes can only be downloaded from the OfficeScan server or Update Agents.
You can speed up the update process by configuring clients to only download pattern files from the ActiveUpdate server. For more information, see ActiveUpdate Server as OfficeScan Client Update Source.
