XP will easily configure the internet system and get it working if you go to the control panel and click "Network" then "Troubleshoot".
If it does not work after that, then one of the accessories is bad or not compatible. It also makes a difference if you connect with a dial-up modem or if using an ethernet card. XP will detect a wireless signal also and configure your modem on newer laptops. Older systems may not have built-in wireless.

yes. it might be a good ideea to upgrade os, windows 2000 or windows xp. try to instal a new network card if you think that your nic is damaged. search for a new pci ethernet card.

If I understand you correctly you have an Intel based MAC, with the boot-camp boot manager, so you can choose to boot either from the native MAC OS or from Windows XP.

The system works fine from the MAC OS, but the (wired) ethernet does not work from XP.

1) When you boot into XP mode, the XP operating system is in
charge and the MAC OS is dormant.

2) Check the XP device manager to see if the ethernet NIC
(network device) is properly installed and if the device
drivers are functioning.

From Windows XP:

Right click My Computer ==> Properties => Hardware ==>
==> Device Manager ==> Network Adapters =>
==> Your network controller

Right click on your network controller ==> properties

Check the device status !!!

2) If the device is NOT working properly, you may need to
download and install a device driver for this card.

3) If the device IS working properly, you may need to run
the NETWORK SETUP WIZARD from the control panel:

START ==> Control Panel ==> Network Setup Wizard ==>
==> Next.

4) Assuming you are connecting to DSL with a login password,
use the: "My computer connect to the internet through a
modem" option.

If your DSL is always on, or if you use a local router to
connect to the DSL modem (the router does the work)

Then you choose the: "My computer connects to the
internet through another computer or a residential gateway"
option.

can you connect that modem first, to a phone line, and run a telnet or dial connection from control panel or accessory ?

SYMPTOMS loadTOCNode(1, 'symptoms'); When you try to establish a dial-up connection after you upgrade your computer to Microsoft Windows XP from Microsoft Windows 98, from Microsoft Windows 98 Second Edition, or from Microsoft Windows Millennium Edition (Me), you may receive an error message that is similar to one of the following: Error 721: The remote computer is not responding. Error 678: The remote computer failed to respond. Error 691: Access was denied because the user name and/or password was invalid on the domain. Error 777: The connection attempt failed because the modem or other connecting device on the remote computer is out of order. To resolve this issue, contact the hardware manufacturer to inquire about how to obtain and install the latest Windows XP-compatible driver for the modem or download an XP driver for the modem

To download the most appropriate modem driver for your Windows XP computer, a few steps is indispensible to finish the whole process.

Step 1
Look at the modem. Write down the make and model. If you have a dial-up modem in your computer, take the panel on the tower off. Shine the flashlight on the device. On the circuit board, the manufacturer and/or model number is present.

Step 2
Locate an Internet connection. To download Windows XP modem drivers, go to the library or someone's home where the Internet is able to connect. If you have another working modem in your house, you can download them directly to your computer.

Step 3
Go to the manufacturer's official website or a Windows XP modem driver's web page. Windows XP Drivers, Drivers Kit and Driver Support Registry have modem drivers for the Windows XP operating system.

Step 4
Click on the modem device. Select the manufacturer of the modem. Some of the driver sites are XP only, while others are all drivers. You will have the chance to choose your operating system before downloading. Click on the "Download" tab. Wait approximately 10 minutes, depending on the speed of the PC and Internet connection.

Step 5
Burn it to a disk. If you are at another location, you need to burn to CD/DVD for transportation.
