If the
Windows Firewall Service when enabled in a Domain the Computer Browser
can't see that computer because the firewall service blocks the service
from other computers. |
The problem with a software solution is it can be changed or hacked.

The best fire wall solution is a hardware solution such as a dedicated
server or router. These instructions apply to Windows XP, Windows Vista, and
Windows 7/8/10.
With that said it is hard to carry your router around with you from place to
place when you travel so the next best thing to not connecting at all is the built
in Windows Firewall.
When the service pack 2 for Windows XP came out it
included a Security Center, incorporated into the Security Center along with
Automatic Updates, Virus notification, is the Windows Firewall Service. If your
computer is a desktop or you don't travel then a hardware solution is the best
and you can use the Win fire wall in conjunction with the hardware if there is no other software
solution.
If your business has a hardware and software solution you will have to
disable the Firewall because it will conflict with the network
hardware / software firewall of the business and you will not have access to the
internet.
When you are traveling or don't have a hardware solution between your
computer and the internet the best solution is to turn on the 'Don't allow
exceptions' setting. You can do this from the Start/Control pane/Window
Firewall. This is on the General tab on the first window. Check the 'On'
(recommended) and then check the box 'Don't allow exceptions'.
By turning on 'Don't allow exceptions' setting the will
reject any queries in bound to your computer
from outside, that is any program trying to contact your computer will be
denied. This does not mean your computer is invisible on the internet, it
means that any attempt to connect to your computer will be refused. This is a
good thing because some virus/trojan/spyware programs try to contact computers,
when they find one open the do their dirty work and infect the computer.
On the
other hand if your computer is already infected
the firewall can not protect your system from contacting the
virus / trojan / spyware
home and giving away your data.
Bottom line is keep it clean! Especially if you
rely on the
Windows Firewall Service.

Under the Exceptions tab you will find a generic list of programs that
are allowed to send/receive from the internet, uncheck any boxes you don't use.
You can add programs here that are not listed such as Eudora E-mail program, you
need to know the ports for the program if you add them to the list, some
programs will have the port assigned when they are installed and the Firewall
program can read the ports from the registry entry.
Things you should know about this Service:
Both the Security Center and the Firewall
services have to be running.
If you have Group Polices in a Domain environment it may disable the
Security Center and Firewall, if this is the case then you will need to contact
your Administrator to setup a 'roaming profile' that allows these
services to run when you are not connected to the domain.
If you use a VPN (Virtual Private Network) to connect to your work or a
special domain you have to know those ports to turn on the exception, this can
not be read from the registry because it is not there, the ports for the VPN are
located in the SAM file which you nor the Administrator of your domain can
access.
If you are using a Hardware only solution (such as a home network with a
router / firewall) you should
use the Windows Firewall also, but if your network has a hardware and a
software firewall solution and you use a 'Proxy' to get outside of the network
for internet access it will interfere with your access, that is why most
businesses that have a hardware and software firewall solution turn off both
Windows Firewall and Security services.
