By manually configuring the properties of the TCP/IP protocol through the properties of a network connection, you can statically assign an IP address, subnet mask, default gateway, DNS servers, and WINS servers. You can also configure manual settings in the Windows Server 2003 Setup Wizard by selecting Custom Settings (as opposed to Typ ical Settings) in the Networking Settings dialog box. To configure a TCP/IP connection manually for static addressing, complete the follow ing steps: 1. Open Network Connections, right-click the appropriate network connection, and then select Properties. 2. In the General tab (for a local area connection) or the Networking tab (all other connections), select the Internet Protocol (TCP/IP) component, and then click Properties. 3. In the Internet Protocol (TCP/IP) Properties dialog box, select Use The Following IP Address, and then do one of the following:

For a local area connection, assign the IP address, subnet mask, and default gateway. For all other connections, assign the IP address.

4. (Optional) In the Preferred DNS Server text box and the Alternate DNS Server text box, type the primary and secondary DNS server addresses. 5. (Optional) To configure a WINS server, click Advanced, click the WINS tab, and click Add to add the address of an available WINS server.

In this practice, you configure a static IP address for Computer1 and an alternate address for Computer2. Until now, your computers have been assigned APIPA addresses.

Note This practice assumes that you have completed a default installation of Windows Server 2003 on both Computer1 and Computer2, and that the two computers are physically networked. It also assumes that you have no other computers on your network.

In this exercise, you review the current IP configuration on Computer1. 1. Log on to Computer1 as Administrator. 2. Click the Start button, and then select Command Prompt.

3. At the command prompt, type ipconfig and then press Enter. This command is used to show your IP address configuration. The output that is produced shows your network connections. Next to Autoconfiguration IP Address, you will see your current address of 169.254.y.z, where y and z refer to the host ID currently assigned to Computer1 by the APIPA feature. The subnet mask is the default of 255.255.0.0. By default, Computer1 has been assigned an APIPA address because a default Windows Server 2003 installation specifies that the IP address of the host is assigned auto matically. In the absence of a DHCP server, the host uses an APIPA address.

In this exercise, you assign a static IP address to Computer1. A static IP address is needed for computers that will later host important network services such as DNS or DHCP. 1. While you are still logged on to Computer1 as Administrator, open Network Con nections, right-click Local Area Connection, and then select Properties. 2. In the This Connection Uses The Following Items area of the Local Area Connec tion Properties dialog box, select Internet Protocol (TCP/IP). 3. Click Properties. 4. In the General tab of the Internet Protocol (TCP/IP) Properties dialog box, select Use The Following IP Address. 5. In the IP Address text box, type 192.168.0.1. 6. Click the Subnet Mask text box to place your cursor inside it. The subnet mask 255.255.255.0 appears in the Subnet Mask text box. Click OK. 7. In the Local Area Connection Properties dialog box, click Close. 8. Log off Computer1.

In this exercise, you alter the IP configuration on Computer2 so that in the absence of a DHCP server, Computer2 assigns itself an IP address that you specify. 1. Log on to Computer2 as Administrator, open Network Connections, right-click Local Area Connection, and then select Properties. In the This Connection Uses The Following Items area, you will see that Client For Microsoft Networks, File And Printer Sharing For Microsoft Networks, and Internet Protocol (TCP/IP) are used by the local area network (LAN) connection.
