Dealing with Problems (Summary)
28
Troubleshooting
Cannot start a network-used
program, or cannot share
files or printers
z
If you cannot start up a program or share files, this may be because the “Firewall
(Windows Firewall)” in the “Windows Security Center” is set to be enabled.
If this function is set to be enabled, damage from viruses and other attacks is
reduced, but some programs and functions cannot be operated.
To use the program or to share files or printers:
You can use programs or other functions without the effects of the Windows Fire-
wall by registering them as an exception in the Windows Firewall settings (it is not
necessary to disable the Windows Firewall).
Note, however, that if a program is registered as an exception, there is a risk of
damage from viruses or other attacks. Before registering a program as an
exception, confirm the program’s safety with the manufacturer or other reliable
source.
A
Select [start] - [Control Panel] - [Security Center] - [Windows Firewall].
B
Select [Exceptions].
C
To register a network game or other programs as an exception:
Select [Add Program], select the program, and select [OK].
To set access through a specified port as an exception:
Select [Add Port], set the port, and select [OK].
To set a file or printer as an exception:
Add the check mark for [File and Printer Sharing].
D
Confirm that there is a check mark for the item to be set as an exception,
and select [OK].
Is it necessary to enable the
Windows Firewall?
z
The Windows Firewall is a security function designed to protect your computer from
unauthorized access via the Internet and other external networks.
The firewall regulates the data exchanged between the computer and the external
network, so that only approved data can pass through. We recommend that you
use your computer with the Firewall enabled to minimize damage from viruses and
other malicious attacks.
z
When installing additional commercially available firewall software, we recommend
that you disable the Windows Firewall settings, as the new software may interfere
with the Windows Firewall functions.
For details, refer to the manual accompanying the firewall software to be installed.
When “Automatic Updates”
is enabled, will all updates
be downloaded (or
installed)?
z
Only Windows Update programs with a high level of priority will be automatically
downloaded (or installed).
Update programs with a comparatively low level of importance will not be down-
loaded (or installed) automatically. Check regularly whether new update programs
have become available.
Security Center warning
function does not operate
z
The Security Center warning function will not operate if you are using a network
domain, for example at a company.
