Dealing with Problems (Advanced)
Cannot start a network-used program,
or cannot share files or printers
If you cannot start up a program or share files, this may be because the “Fire-
wall (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
Firewall 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.

wall].

Is it necessary to enable the Windows
Firewall?
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 exter-
nal 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.
When installing additional commercially available firewall software, we recom-
mend 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.
