Firewall Software
When you use the notebook for e-mail, network, or Internet
access, it is possible for unauthorized persons to obtain
information about you, your notebook, and your data. To protect
your privacy, it is recommended that you use firewall software.
Firewall software monitors all incoming and outgoing traffic on
your notebook and includes features such as logging and
reporting, automatic alarms, and displays that you can use to
configure the firewall.
The Windows operating system firewall is available on your
notebook and is enabled by default. To learn more about this
firewall or to disable or reenable this firewall:
1. Select Start > Control Panel > Network and Internet
Connections > Windows Firewall.
2. Select the General tab.
❏ To learn more about Windows Firewall, select the What
else should I know about Windows Firewall? link.
❏ To disable Windows Firewall, select Off (not
recommended).
❏ To reenable Windows Firewall, select On
(recommended).
3. Select OK.
✎
Under some circumstances a firewall can block access to
Internet games, interfere with printer or file sharing on a
network, or block authorized e-mail attachments. To temporarily
solve the problem, disable the firewall, perform the task that is
interfering with the firewall, and then reenable the firewall. To
permanently resolve the problem, reconfigure the firewall.
