Chapter 17: Mastering Dial-Up, Broadband, and On-the-Go Networking
Creating VPN Connections
Many organizations use VPN connections to gain access to their networks. These con-
nections use encryption to secure the transmitted data between the user and the net-
work. They also provide remote connectivity to a network so that you can access
network resources, such as file shares, email servers, and terminal service connections.
Most organizations use Internet connections to allow VPN client connections to their
network. If you do not have the correct information to connect to the VPN service,
contact your network administrator for specific information on how to connect to the
network. Some organizations use specific VPN client applications, which require the
installation of a separate VPN client application. To determine whether the default
VPN client included in Windows Vista will work with your VPN connection, contact
your network administrator. If your organization is running Microsoft’s Routing and
Remote Access Service (RRAS), the VPN client in Windows Vista will work by default.
In the Network and Sharing Center, you can set up a VPN connection by following
these steps:
1. Click “Set up a connection or network” in the left pane. This opens the “Set up a
connection or network” Wizard.
2. In the wizard, click “Connect to a workplace,” and click the Next button.
3. If your computer has existing connections that could be used to connect to your
workplace, you’ll see a list of the existing connections. Select “No, create a new
connection” and then click Next.
4. On the “How do you want to connect?” page, you have two choices:
Use my Internet connection
This feature connects you to a workplace using a VPN connection through
the Internet. It requires a username and password for connecting to your
VPN server.
Dial directly
This feature connects you to a workplace using a VPN connection with a
modem by directly dialing a phone number to your workplace without
going through the Internet.
To use an existing Internet connection for a VPN connection, follow these steps:
1. Click “Use my Internet connection (VPN)” to use an Internet connection for a
VPN connection.
2. If you aren’t currently connected to the Internet, you’ll see the “Before you con-
nect” page. On this page, choose the connection that you want to use to con-
nect to the Internet, and then click Next.
3. On the “Type the Internet address to connect to” page, shown in Figure 17-15,
type the IP address provided by your network administrator. This is the IP
address of your organization’s remote access server.

4. In the “Destination name” text box, type a name for the connection. The default
name is VPN Connection.
5. Check “Use a smart card” if you have a smart card for use in authenticating you
to your VPN connection.
6. Check “Allow other people to use this connection” if you want anyone with
access to your computer to be able to use this VPN connection.
7. Check “Don’t connect now; just set it up so I can connect later” if you want to
create the VPN connection, but not actually connect to it.
8. Click Next. On the “Type your user name and password” page, the wizard
prompts you to enter your username and password. In the “User name” text box,
enter the domain username for your workplace. In the Password text box, enter the
password for your domain user account. As necessary, click “Show characters” to
view your password. This helps you identify the correct syntax and find typos.
9. Click “Remember this password” to save your password for future use.
10. As necessary, enter the name of the domain at your workplace into the Domain
text box. This setting is optional, but it remembers your domain so that you do
not have to type it in each time you use the connection.
11. After entering the correct data into the fields provided by the wizard, click the
Connect button to create and establish your broadband VPN connection.
