The OfficeScan server is the standard update source for clients. 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 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 client quits the update process.
