Customized Update Sources for OfficeScan Clients

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 customized update sources for clients:

• Updates > Networked Computers > Update Source

1. Select Customized Update Source and click Add.

2. In the screen that displays, specify the clients’ IP addresses. You can type an IPv4 range and/or an IPv6 prefix and length.

3. Specify the update source. You can select an Update Agent if one has been assigned or type the URL of a specific source.

• Ensure that the clients can connect to the update source using their IP addresses. For example, if you specified an IPv4 address range, the update source must have an IPv4 address. If you specified an IPv6 prefix and length, the update source must have an IPv6 address. For details about IPv6 support for client updates, see OfficeScan Client Update Sources.

4. Click Save.

5. Perform miscellaneous tasks in the screen.

1. Select any of the following settings. For details on how these settings work, see Client Update Process.

• Update components from the OfficeScan server if all customized sources are unavailable or not found

• Update domain settings from the OfficeScan server if all customized sources are unavailable or not found

• Update client programs and hot fixes from the OfficeScan server if all customized sources are unavailable or not found

2. If you specified at least one Update Agent as source, click Update Agent Analytical Report to generate a report that highlights the update status of clients. For details about the report, see Update Agent Analytical Report.

3. Edit an update source by clicking the IP address range link. Modify the settings in the screen that displays and click Save.

4. Remove an update source from the list by selecting the check box and clicking Delete.

5. To move an update source, click the up or down arrow. You can only move one source at a time.

6. Click Notify All Clients.

Client Update Process

• This topic discusses the update process for clients. The update process for Update Agents is discussed in another topic. For details, see Customized Update Sources for Update Agents.

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

1. A client updates from the first source on the list.

2. If unable to update from the first source, the client updates from the second source, and so on.

3. If unable to update from all sources, the client checks the following settings on the Update Source screen:

   Additional Settings for Custom Update Sources

   Setting	Description
   Update components from the OfficeScan server if all customized sources are unavailable or not found	If this setting is enabled, the client updates components from the OfficeScan server. If disabled, the client 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 is not included in the Customized Update Source List. 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.
   Update domain settings from the OfficeScan server if all customized sources are unavailable or not found	If this setting is enabled, the client updates domain-level settings from the OfficeScan server.
   Update client programs and hot fixes from the OfficeScan server if all customized sources are unavailable or not found	If this setting enabled, the client updates programs and hot fixes from the OfficeScan server.

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