In Windows XP Professional, all of the processes for creating network connections are consolidated in the New Connection Wizard. Inbound connections are one of the types of network connections created using the New Connection Wizard.
To configure and administer inbound connections on a computer running Windows XP Professional, you use the New Connection Wizard. To access the New Connection Wizard, click Start, click My Computer, click My Network Places, click View Network Connections, and then click Create A New Connection. Windows XP Professional displays the Welcome To The New Connection Wizard page. Click Next to continue, and Windows XP Professional displays the Network Connection Type page. To configure an inbound connection, click Set Up An Advanced Connection and then click Next. The New Connection Wizard displays the Advanced Connection Options page (see Figure 17.1).
On the Advanced Connection Options page, click Accept Incoming Connections and then click Next to display the Devices For Incoming Connection page.
The Devices For Incoming Connections page allows you to choose one of the available devices on your computer to accept incoming calls. If the device you select is configurable, click Properties to configure it. For example, if you have selected a modem, possible options to configure in the device's Properties dialog box include port speed, error correction, use of compression, and the type flow control (see Figure 17.2). The Advanced tab contains additional configurable options, which might include the number of data bits, the parity, the number of stop bits, and the modulation type.
When you are through configuring the device, click OK to close the Properties dialog box and then click Next in the Devices For Incoming Connection page. The New Connection Wizard displays the Incoming Virtual Private Network (VPN) Connection page. If you click Allow Virtual Private Connections, Windows XP Professional modifies the ICF so that your computer can send and receive VPN packets. Select the option either to allow or not allow VPN connections, and then click Next.
You must specify which users can use this inbound connection in the User Permissions page (see Figure 17.3).
After you select a user, click Properties. In the user-name Properties dialog box, click the Callback tab to set the callback options. You can choose Do Not Allow Callback, Allow The Caller To Set The Callback Number, or Always Use The Following Callback Number. Enabling callback causes the remote server, in this case your computer, to disconnect from the client calling in, and then to call the client computer back. By using callback, you can have the bill for the phone call charged to the office phone number rather than to the phone number of the user who called in. Callback can also be used to increase security because if you specify the callback number you don't have to worry about someone trying to break in. Even if an unauthorized user calls in, the system calls back at the number you specified, not the number of the unauthorized user.
After you specify the callback options, click Next. The New Connection Wizard displays the Networking Software page. You can choose the networking software you want to enable for incoming connections. You can also install additional networking software by clicking Install. For example, to install NWLink IP/SPX/NetBIOS Compatible Transport Protocol, click Install, select Protocol, and then click Add. On the Select Network Protocol page, select NWLink IP/SPX/NetBIOS Compatible Transport Protocol, insert the Windows XP Professional CD-ROM in the CD-ROM drive, and then click OK. Windows XP Professional installs the protocol. After the protocol is installed, you are returned to the Networking Components page. When you click Next, you will be prompted to type a name for the connection, and then click Finish. If you would like a shortcut to appear on your desktop, select the Add A Shortcut To My Desktop check box. Click Finish to create the connection.
In this practice, you use the New Connection Wizard to configure an inbound connection.
