When initiating updates, OfficeScan clients first get updates from the update source specified on the Updates > Networked Computers > Update Source screen. If the update is unsuccessful, the clients attempt to update from the OfficeScan server. Selecting this option enables clients to attempt to update from the Trend Micro ActiveUpdate server if the update from the OfficeScan server is unsuccessful.
Selecting this option forces the selected clients to always run scheduled update except when users have the privilege to enable/disable scheduled update and the user disables scheduled update. See Component Update Privileges for details about the privilege.
Specify the update schedule in Updates > Networked Computers > Automatic Update > Schedule-based Update.
This option allows component updates to proceed but prevents hot fix deployment and client upgrade.
If you do not select this option, all clients simultaneously connect to the server to upgrade or install a hot fix. This may significantly affect server performance if you have a large number of clients. If you select this option, plan how to minimize the impact of client upgrade or hot fix deployment on the server and then execute your plan.
