The first step in connecting a computer to a Windows Small Business Server 2003 network is to connect to the network and obtain a valid IP address. This process is pretty simple: plug the computer into an Ethernet switch on the internal network, and configure the system for Dynamic Host Control Protocol (DHCP). Wireless clients must first associate with an access point and provide a WPA/WEP key.

Configuring Windows XP and Windows Server 2003 to Use DHCP To configure computers running Windows XP or Windows Server 2003 to use DHCP for TCP/IP configuration, complete the following steps:

1. In the Network Connections folder (available in Control Panel), rightclick the appropriate network adapter (most likely Local Area Connection), and choose Properties from the shortcut menu. 2. In the Local Area Connection Properties dialog box, select the Internet Protocol (TCP/IP) component, and click Properties. The Internet Protocol (TCP/IP) Properties dialog box appears (Figure 12-4).

Figure 12-4.

3. Verify that the Obtain An IP Address Automatically and Obtain DNS Server Address Automatically options are selected, and then click OK. Note You might want to use static IP addresses for additional servers (print servers and additional domain controllers are two likely candidates). If you choose to use a static IP address, configure the server with an IP address in the excluded IP address range of 192.168.16.3 through 192.168.16.9, or add an appropriate exclusion in DHCP .

Configuring Windows 2000 to Use DHCP To configure Windows 2000 clients and servers to use DHCP for TCP/IP configuration, complete the following steps:

1. In the Network And Dial-Up Connections folder (available in Control Panel), right-click the appropriate network adapter (most likely Local Area Connection), and choose Properties from the shortcut menu. 2. In the Local Area Connection Properties dialog box, select the Internet Protocol (TCP/IP) component and click Properties. The Internet Protocol (TCP/IP) Properties dialog box appears (Figure 12-5).

3. Verify that both the Obtain An IP Address Automatically and Obtain DNS Server Address Automatically options are selected, and then click OK.

Associating with a Wireless Access Point Windows XP clients can use the Zero Configuration Wireless feature to easily associate with wireless access points and provide appropriate network keys, as discussed in the following steps. All other clients must use the interface provided by the network adapter drivers.

Note Pocket PC 2003 devices provide a feature called Zero Configuration Wi-Fi, which works almost identically to the Zero Configuration Wireless feature in Windows XP . 1. After installing and configuring a wireless network adapter, right-click the Wireless Network Connection icon in the system tray, and choose View Available Networks from the shortcut menu. 2. Select your wireless network in the Wireless Network Connection dialog box, shown in Figure 12-6.

Figure 12-6.

3. Type the network key (WPA or WEP) in the Network Key and Confirm Network Key boxes, and then click Connect. If you re using 802.1X authentication, as discussed in 17, Customizing a SharePoint Web Site, leave the Network Key box empty and select the Enable IEEE 802.1X Authentication For This Network check box. (See 15, Managing Connectivity, for more help with 802.1X.) If you re using WPA, see the Real World sidebar, Getting Connected with WPA Authentication. Real World Getting Connected with WPA Authentication Using Wi-Fi Protected Access (WPA) for wireless client authentication and encryption is one convenient method of securely connecting wireless clients to an internal network, though you must clear a few implementation hurdles before everything works properly.

To use WPA for wireless authentication, clients must run Windows Server 2003 or Windows XP SP1 with the Microsoft WPA client program (discussed in Microsoft Knowledge Base Article 815485 and likely included in future service packs). To use WPA on other operating systems, purchase a third-party WPA supplicant unless one is provided with the network adapter drivers. Two popular third-party WPA supplicants are Funk Software s Odyssey client (http://www.funk.com/radius/wlan /wlan_c_radius.asp) and Meetinghouse Data Communications AEGIS client (http://www.mtghouse.com/products/client/index.shtml). Because many wireless network adapters rely on the Microsoft WPA client program for WPA support, computers that don t have this or a third-party WPA supplicant installed might have to connect to the network via Ethernet cable to download and install WPA support, or install the latest service pack and WPA client from removable media before connecting to the network.
