There are a number of checks you can make yourself if having difficulty accessing the network
1. Is the light on the back of the network card on?
Most network cards have lights on them indicating that they are communicating with the network, if these lights are not on when the computer is switched on then it is likely that the network card is faulty or not fitted correctly. Also, check that the network cable is attached to the RIGHT-HAND wall socket. The network card is indentified by the slot into which you put the ethernet cable to connect to the network.
2. Can you make contact with other machines on the network?
The helpdesk may ask you to try pinging another, pinging a computer just involves sending a very small message asking the other computer to respond.

If your computer does not work in your own room, see if it can connect elsewhere. Also, check whether another computer works in your room. This will help to show if it is a problem with your computer or the network point.

7. What is the MAC address of your network card?
If you are having problems connecting to the network, one of the first checks that the helpdesk will make is to see if your card has been registered correctly, to do this they will need the MAC address of your network card. (This is a unique identifying number that all network cards have, in the format 00:05:5D:06:EA:94)

Your Ethernet address is under the TCP/IP tab, and will look something like 00:05:5D:06:EA:94 |

This is caused by another network user incorrectly configuring their equipment (computers should be set to obtain their IP details from DHCP). Please report this to the helpdesk.
