Answer 1

Your picture, do you live in a famine area.

Answer 2

If the DHCP server at the school is set to give out IPs like 192.168.1.1XX and the computer you're working on is set to statically use another IP, you'll get that error. Also, if the patch cable you're using is damaged (all the wires not in the connector all the way) you'll get that error. Look at the settings on the network card (right click "my network places", go to "properties") and make sure the network card is set to "obtain an IP address automatically" under TCP/IP settings. It could also be a duplex setting on the NIC being in conflict with the school's network - but I seriously doubt that's the case since 99.9% of the world's population have never heard of a duplex setting and thus they wouldn't mess with it. If you want to check it out, just set it to "auto" or 100/full if you don't have the auto option for some reason.

Answer 3

It means that the firewall is blocking some or all of the network traffic. You will have to configure the firewall to fix this. Also make sure that the computer is on the correct subnet (For instance if the server IP is 198.168.2.1 make the computer's IP 198.168.2.100)

Try to see if you have an IP address or not. Go to Network Connection (in WinXP) and select the network card you are currently using. It should be shown on the left panel of the network connections page. Or you can right-click > status > support.

If there is none (or it's full of zeroes) then go to Run..., type in cmd.This will open a DOS box. Make sure you have your Modem connected wired to your computer. Type in ping [modem's IP]. The IP should be written somewhere with the modem's manual. If it can send the package then try to access to your modem using Internet Explorer (by typing in its IP). The admin password should be somewhere in the modem's manual. Setup you modem as shown in your manual then try again.

Contact your school's network admin for information on how to setup your modem to connect to the system. It usually needs a certain password/IP/ID...etc.

or try the next step.

In the DOS box, type in ipconfig/release then type in ipconfig/renew. If your IP does not renew, try to reboot your modem. Turn off, turn on. Then try to do the ipconfig/release, ipconfig/renew.

If this doesn't work either then try to Reset your modem. This is shown in the manual.

By this time it should be working the next few steps mean there is something wrong with your Windows or the modem or one of the hardware/drivers.

To see if the modem is working or not, try to have someone else access to your modem (a PC of a friend near by). If your modem doesn't work then you better replace it. If it works then there is something wrong with WinXP or the network card.

If there is something wrong with WinXP (it happens sometimes) then you can try to reinstall your network card or roll back to an earlier period.

Answer 5

I have the exact same problem with my laptop. I usually just pop the wireless card out and put it back in again. After that it normally works. I don't think it's actually your computer thats causing the problem. My theory is that it has something to do with the school's wireless.

Answer 6

unplug the modem for 30 seconds and then plug it back in. the firewall most likely has nothing to do with it. its probably your ISP.

Answer 7
