Users can check for updates manually at any time. In addition, you can configure optional policy settings for updating tasks.

Update support for some operating systems is ending. Once support ends, client computers running those operating systems will no longer be protected against new threats. See Operating system support ending on page 28 for more information.

Update automatically

The software on each client computer automatically connects to the Internet directly or to a relay server and checks for updated components. Enforced Client checks for updates five minutes after a user logs on and at regular intervals thereafter. For example:

„If a computer is normally connected to the network all the time, it checks for updates at regular intervals throughout the day.

„If a computer normally connects to the network each morning, it checks for new updates five minutes after the user logs on each day, then at regular intervals throughout the day.

„If a computer uses a dial-up connection, the computer checks for new updates five minutes after dialing in, then at regular intervals throughout the day.

By default, computers check for new updates every 12 hours. You can change this interval by configuring a policy setting (see Select your update frequency on page 97).

On computers where a CHAP or NTML proxy is set up in Internet Explorer, automatic updates do not work.

Update manually

At times, users might want to check for udpates manually. For example, when a computer appears to be out-of-date in your administrative reports, users might need to update manually as part of the troubleshooting process.

To update manually:

Double-click in the system tray, or click the icon and select Update Now.

Update during an outbreak

When an outbreak is identified by SonicWALL Avert Labs, they issue an outbreak DAT, which is a special detection definition (DAT) file marked as Medium or High importance. It is specially encoded to inform the first computer receiving it to share the update immediately with other client computers on the network.

In rare cases, SonicWALL might send an EXTRA.DAT file with instructions for manually installing it.
