Networking TCP IP in Winxp


To connect to the Accommodation Network you will need a network adaptor/card installed on your computer.

If do not have a built in network adaptor and have yet to install your network card, then you first need to install it as follows:

  • For laptop computers, it should be simply a case of turning the computer on, plugging the card into an available PCMCIA slot and following the instructions to make sure the correct drivers are installed.
    If you have a desktop/tower computer then you will need unplug the computer from the mains supply, remove the case and remove the appropriate blanking plate so that the network card can be fixed into a suitable slot taking anti-static precautions. Then plug the computer back in, turn it on and follow any instructions provided with the card or by Windows.


Checking Your Network Adaptor/Card

To check that the network adaptor/card is installed properly you can look for it in the Device Manager. To open the Device Manager, click the Start button and select Control Panel (this is in the Settings option of the menu for XP with the Classic Start menu). In the Control Panel, click on the Performance and Maintenance icon, and then click the System icon to open the System Properties window (if you have switched the control panel to classic view the System icon will already be shown in the Control Panel). Click on the Hardware tab and then click on the Device Manager button.

In the Device Manager window, click on the + symbol next to Network adapters and your network adaptor/card should be listed under that section if it has been installed.

If the network adaptor/card has a yellow ! (exclamation mark) or a red X (cross) next to it or if its listed in a ? section, the adaptor/card has not been installed properly and its probably best to delete/uninstall the drivers and restart Windows to make it reinstall the adaptor/card.

If no network adaptor is shown, you either do not have a network adaptor/card, it is not fully plugged into your computer or it is disabled in the BIOS. If you are using a network card, its best to refit the network card making sure its fully pushed into the computer.



Opening the Network Connections Window

From the Start menu, open the Control Panel, then do one of the following:

  • Click on Network and Internet Connections and then click on Network Connections. (Category View).
    Double-click on Network Connections. (Classic View).

This will show a Network Connection window, which will show your Local Area Connection.



Entering Your Host Name

In the Network Connections window (opened as described above) click on the menu option Advanced and choose Network Identification to bring up the System Properties dialog box. In the box Computer description you can enter anything. Whatever you enter may be visible by others browsing the network.

Next you need to make sure your computer is configured with a unique "Computer name", otherwise you may get an error message "A duplicate name exists on the network". This is unlikely to be required for computers that are already configured for other networks and so only need to do this if you get the error message described above.

Note: If your computer is already configured for use on a Domain, then do not modify the "Computer name", Domain or workgroup settings in any way (as described in the step below), as this will affect the way your computer works. Simply skip the following step.

Click on the button Change to bring up the Computer Name Changes dialog box. Here you should enter your hostname into the Computer name field and SA in the Workgroup field, as shown below.

Click OK to close the Computer Name Changes dialog box. Click OK to exit the System Properties dialog box.

You may find that these are the only settings that need to be entered, so you might want to try the network connection. If you find the connection does not work then proceed to the following step to make sure there are no settings entered from a previous internet connection.



Checking / Installing TCP/IP

In the Network Connections window (opened as described above), right click on the icon for the Local Area Connection and from the menu that appears, choose Properties.

The Connect using field should display your ethernet card.

The component Internet Protocol (TCP/IP) must be present and shown with a √ (tick) in the check-box. If it is not present, click Install, select Protocol, click Add, select Internet Protocol (TCP/IP) and click OK.

If you do not wish to share any of your files or printers with other computers, you may improve the security of your computer by removing the √ (tick) in the check-box for File and Printer sharing for Microsoft Networks.

Highlight Internet Protocol (TCP/IP) and click on the Properties button. The option Obtain an IP address automatically should be selected together with Obtain DNS server address automatically.

Click on the Advanced button to show the Advanced TCP/IP Settings dialog box.

If you have any IP addresses entered in the Default Gateways area these should be removed. The IP settings dialog box should be as shown below.

Click the DNS tab and remove any IP addresses from the DNS server addresses area. Remove any √ (tick) against the Register this connection’s addresses in DNS option.

Click the WINS tab. Select the option Default: Use NetBIOS setting from the DHCP server and remove any √ (tick) from the option Enable LMHOSTS lookup. Any IP addresses in the WINS addresses area should be removed.

Click OK to close the Advanced TCP/IP Settings dialog box. Click OK to close the Internet Protocol (TCP/IP) Properties dialog box. Click Close to close the Local Area Connection Properties dialog box.

If asked to restart your computer click Yes.

Once your computer has successfully been registered for use on the Accommodation Network and the connection activated, you should be able to browse the web and use other supported programs.
