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).
Note
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appears to be out-of-date in your administrative reports, users might need to update manually as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.
Note
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.
On computers where a CHAP or NTML proxy is set up in Internet Explorer, automatic updates
do not work.
In rare cases, SonicWALL might send an EXTRA.DAT file with instructions for manually
installing it.
