13. Summary of Current week’s learning outcomes This week, you will achieve the following: - 1.) Setting up a peer to peer network including configuring host IP addresses and testing connectivity. 2.) Set up a network for others’ to troubleshoot

14. Steps Taken When Setting up a Network • In order to set up a network, you firstly need to check that all PC’s involved have a NIC installed. • Also, make sure that you have the necessary Cable, Wall sockets, modules, patch panels, patch leads, RJ 45 connectors, trunking, Hubs, Switches and Routers etc. • Once all the hardware and layer 1 cabling infrastructure is in place, then it’s time to set up the software side of the network. • Each operating system is different, but the stages here are based on a Windows XP operating system.

15. Step 1 • Ghost / Install O/S & service packs and/or drivers. • If the PC to be networked is new, then no O/S will exist, usually manufacturers provide ghost CD’s to build the O/S directly onto the HD. • You may have to install a new O/S, or upgrade the O/S. • Once the O/S is installed or upgraded, it is time to install the service packs. • Go to Control Panel and check Device Manager for hardware and Interrupt conflicts. You are looking for yellow ? Next to devices. • If the PC has specialist cards or hardware or has conflicts, you may need to install additional vendor specific drivers in order to get all devices to work correctly.

16. Step 2 • Run network Installation Wizard • Go to Control Panel and click the Network Connections icon and run the network installation wizard. • The wizard will take you through each stage of the network setup process. • Specify a Computer Name, the Workgroup, The Network Type(peer to peer, Client, Web based etc.) • Click OK to confirm your settings • You can let windows assign its own IP Address via DHCP or you can configure an IP Address yourself.

17. Step 3 • Check Connectivity • Assuming you have tested all aspects of the physical medium and horizontal cabling structure before starting step 1, you need a simple way to check your computer is connected to the network. • Load the Command Prompt(DOS Prompt) and use the command IPCONFIG /ALL to find assigned IP addresses of the PC’s on your network. • Use the PING command to ping computers on your network. If you receive a reply, then your network is working correctly. • You could click on the Network icon on the desktop but this method of testing if each computer is connected is very slow and unreliable, as you have to keep refreshing the window all the time as you make changes to the network.

18. The DOS Prompt Microsoft Windows 2000 [Version 5.0] • Start, Run, Type CMD <Enter> - which is the quickest way to access an MS DOS window. Very useful for troubleshooting, especially if you have not got the rights to get to the control panel in Windows. C:\

19. Find out your Workstation Settings with IPCONFIG Microsoft Windows 2000 [Version 5.0] • IPCONFIG can be typed into the NOS CLI (DOS window) to find out the network settings for that workstation. IPCONFIG /ALL will display all settings including NIC MAC address C:\ ipconfig /all <enter>

20. Step 4 • Implement the Corporate IP addressing scheme • IF an organisation is using it’s own IP addressing scheme (not one assigned by DHCP) then each PC on the network will need the following settings changing: - • Go into Control Panel, Click on the network Connections icon, then right click on Local Network icon then select Properties from the drop down list. • This loads up the network settings window. • Select TCP/IPthen Click the Properties button. • Enter the IP Address, Subnet Mask and Default Gateway for that PC then click OK to save the changes. • Use step 3 to test network connectivity again if necessary.

21. Configuring Hosts • A host computer can be assigned an IP address by a network administrator or automatically from a DHCP server. • To allocate an IP address to a host you will need to access the control panel, then click on the network icon; right click on the network connection an view the properties. (will vary depending on O/S)

22. Configuring Hosts • You then need to enter the hosts IP Address. • The subnet mask – identifies how many bits have been borrowed to identify subnet. • The Default Gateway – Address of gateway interface. • DNS server IP Address – location of DNS server.

23. Step 5 • Test your network • Use Command prompt to check IP address on the local host to see it it correct and change if necessary, repeating step 4. • Use Command Prompt to Ping other hosts on your network to check that your changes have worked.

24. Test NIC Function with PING Microsoft Windows 2000 [Version 5.0] • PING 127.0.0.1 can be typed into the NOS CLI (DOS window) to find out if the NIC is working or not. This IP Address is called a loopback address. C:\ ping 127.0.0.1 <enter>

25. Any Questions ???? ••Please feel free to ask any questions related to the topics discussed in this lecture. Now its your turn to try!!

26. Summary of Practical work • Now it is your turn to check the setup of your network setup in Virtual PC and see if you have connectivity with others’ • Change your IP addressing scheme using a 192.168.20.0 network and re-configure your IP Addresses. • Work in groups to create a star network (1 switch – 5 PCs) in Packet Tracer. Introduce 2 faults for your peers to find and fix.

27. The End ••During the next lecture, we will be looking at the following: - The OSI model.
