■ You can view all network connections configured on a computer in the Network
Connections window, which you can access through Control Panel. In the Network
Connections window, you can right-click a connection to access command
for renaming, disabling, and repairing a connection. You can also open a connection’s
Properties dialog box to configure advanced options.
■ Dial-up connections work much like LAN connections, but they have additional
options that let you control when the connection is dialed, the number for the
connection, and other criteria for use. To create a dial-up connection, you use the
New Connection Wizard. You can also configure Windows XP Professional to
allow incoming dial-up connections.
■ Windows XP Professional can operate in two wireless modes: ad-hoc wireless networking,
in which there are multiple stations but no AP, and infrastructure wireless
networking, in which stations connect to an AP. You can secure wireless networks
in the following ways:
❑ By filtering MAC addresses so that only specified computers can connect to
an AP
❑ By disabling SSID broadcasts so that casual intruders will not detect the wireless
network
❑ By using WEP encryption, which is widely supported but also has widely recognized
flaws
❑ By using WPA encryption, which provides stronger encryption than WEP
■ ICS lets one computer with an Internet connection share that connection with
other computers on the network. The computer running ICS always configures
itself with the IP address 192.168.0.1. That computer also acts as a DHCP server
and gives other computers on the network addresses in the 192.168.0.2 through
192.168.0.254 range.
■ Windows Firewall is a software-based firewall built into Windows XP Professional.
Windows Firewall blocks all incoming network traffic except for solicited traffic
and excepted traffic. You can enable or disable Windows Firewall globally for all
network connections on a computer, or enable and disable it on individual connections.
