Peer-to-Peer Network In a peer-to-peer network, devices are connected directly to each other without any additional networking devices between them, as shown in Figure 68. In this type of network, each device has equivalent capabilities and responsibilities. Individual users are responsible for their own resources and can decide which data and devices to share. Because of that, the network has no central point of control or administration. Figure 1. Peer-to-Peer Network

It allows certain files and folders to be shared with everyone or with selected users. Peer-to-peer networks are quite common in small offices that do not use a dedicated file server. Files and folders can be configured to allow network users to copy them, but not alter them in their original location, which is a common safety precaution. However, files and folders can also be assigned a "read/write" status that allows either selected users or all users on the network to change them.

Peer-to-peer networking differs from client-server networking, where certain devices have responsibility for providing or "serving" data and other devices consume or otherwise act as "clients" of those servers. Setting up a peer-to-peer network in Windows XP The steps described below are provided as a general guide that will work for most home networking situations. However, it may not work for all scenarios. Do the following steps to set up your own inclusive home network: 1. Make sure both systems have Network Interface Cards (NICs) installed and are using the proper cables. NOTE: For a direct network cable connection between two PCs (not with a hub, switch or router), you need to have a cross-over cable. 2. For PCs with Windows XP, the home networking wizard can be used to set up Windows for your network. a. Click Start, and then Control Panel. b. Select Network and internet connections. c. Double-click Network setup wizard and follow the on-screen instructions. . NOTE: If the Network setup wizard is unsuccessful, continue with the steps below. 3. Click Start, Control Panel, Network and Internet Connections, and then Network Connections. At Network Connection Windows, you will see the Local Area Connection Icon, Right click it and select Properties. Local Area Connection window appears.

4. Click on the General tab.

Figure 2. LAN Properties General Tab 5. A device name should appear under "connect using." If not, there is a hardware issue and Windows is not recognizing the network hardware. This issue must be fixed before continuing. a. At the General Tab, Put a check mark at the following: - Client for Microsoft Network - File and Printer Sharing for Microsoft Network - Internet Protocol (TCP/IP) b. Put a check mark saying Show icon in notification area when connected. c. Select the Internet Protocol (TCP/IP) and click the Properties button NOTE: If any of the above component is not installed, install them by selecting Add or Install, and then selecting the missing component, and clicking Add.

Figure 3. TCP/IP- Properties d. At the IP Address tab, select Specify IP Address. e. Enter 192.168.0.1 as the unique IP Address for the first machine. For each other PC add one to the last number in the IP address. For example,  KIDSPC1 = 192.168.0.1 ,  MOMSPC2 = 192.168.0.2 ,  and WORKPC3 = 192.168.0.3 . NOTE: 192.168.0.x is an IP Address reserved for private networks and is not routable to the Internet.

Figure 4. Assigning IP Address and Subnet Mask 4|Page

6. In the Subnet mask field enter: 255.255.255.0 All PCs on the same network use the same subnet mask. Click the Ok button to finish configuration and to close the Local Area Connection Properties windows. Note: The Domain Name System (DNS) is optional. If you have a DNS system and your connected to ISP you can input an IP address which came from the DNS server. Click Start, right-click My Computer, and then select Properties. 7. Click the Computer Name tab and click the Change button. 8. Enter a name that describes the PC in the Computer Description field. For example, KIDSPC1, MOMSPC2, or WORKPC3. 9. Enter the workgroup name for your network. Use the same workgroup name for all PCs on the network. Spelling is important in this step. 10. Repeat these steps for each PC on the network. 11. Wait two minutes after Windows opens on all PCs, and then double-click the Network Neighborhood icon on the desktop. If all went well, you should see all the PC names on the network when files and folders are being shared. If you do not see them, press F5 to refresh the screen. 12. If after refreshing the network window, the other PCs still do not appear, check the firewall settings that may be interfering with the communication. Setting up a Peer-to-Peer network in Windows 7 If you are going to work with Windows 7 operating system, the following procedures are used to set up a peer-to-peer network: 1. On Desktop ==> Select My Computer ==> Right Click ==> Select properties.
