Working with the Windows Firewall
Management. Verify that the service status is listed as Started, and make sure the
“Startup type” is set to Automatic. If the service is not listed as Started, click the Start
button to start the service. Also, verify the logon credentials using the Log On tab
associated with the service’s Properties dialog box. You should see “Local service” as
the selected account.
If the firewall still isn’t working properly, you need to verify the network location.
When you click the Windows Firewall option in the Windows Security Center, the
main firewall window shows the network location. If you are on a private or domain
network, other computers should be able to connect to you by default. If you are on
a public network, most types of connections to your computer are disabled. If the
wrong location type is listed, you can change the location type in the Network and
Sharing Center by clicking the network’s Customize link, selecting the desired loca-
tion type, clicking Next, and then clicking Finish. Don’t change the location type
without first considering the possible ramifications of doing so. If you are on a pub-
lic network and you specify that you are on a private network, you will open your
computer to attack.
