Keeping Protection Up-to-Date
Tip: 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.
3. If unable to update from all possible sources, the client quits the update process.
Client Update Methods
Clients that update components from the OfficeScan server or a customized update
source can use the following update methods:
Automatic Update
Client update runs automatically when certain events occur or based on a schedule. For
details, see Automatic Update on page 4-27.
Manual Update
When an update is critical, use manual update to immediately notify clients to perform
component update. For details, see Manual Update on page 4-31.
Privilege-based Update
Users with update privileges have greater control over how the OfficeScan client on
their computers gets updated. For details, see Update Privileges on page 4-33.
Automatic Update
Automatic update relieves you of the burden of notifying all clients to update and
eliminates the risk of client computers not having up-to-date components.
In addition to components, OfficeScan clients also receive updated configuration files
during automatic update. Clients need the configuration files to apply new settings. Each
time you modify OfficeScan settings through the Web console, the configuration files
change. To specify how often configuration files are applied to clients, see step 3 below.
Note: You can configure clients to use proxy settings during automatic update. See Proxy for
Client Component Update on page 4-34 for details.
