    I need some help here.

    I work in a small office where we have about 10 computers on a LAN. Recently I upgraded one of our computers to XP Pro with SP3. It ran fine for about two weeks and then the internet started to not work. I "repaired?" the network connection and it worked for about 5 minutes and went down again. It seems like it is sending data but not receiving. I have done a lot of research and tried many suggestions on a few forums and nothing has helped. I even reformated the hard drive and reinstalled windows xp...still nothing. I know my way around computers enough to follow directions if anyone can help it would be appreciated!

    Please show ...

    Start, Run, CMD, OK to open a command prompt:
    (For Vista or 7 type CMD in the Search box after Start)

    Type the following command:

    IPCONFIG /ALL

    [Note that there is no space between the slash and ALL.]

    Right click in the command window and choose Select All, then hit Enter.
    Paste the results in a message here.

    If necessary use a text file and removable media to copy the results to a computer with internet access.

    That shows an apparently good IP configuration. If it represents a time when you had internet access please show another one for when internet access has been lost.

    If it represents a time when you did not have internet access my top suspect is a non-Windows security application that has become corrupted. What one(s) are on the machine? Best to uninstall, run the Removal Tool if one is provided, and then run the stack repairs posted below. You can reinstall after testing.

    In case of corrupted NIC driver use Device Manager to uninstall the Broadcom adapter; reboot and let Windows discover the adapter and reinstall the driver.

    (From a JohnWill post)

    TCP/IP stack repair options for use with Windows XP with SP2 or SP3.

    Start, Run, CMD, OK to open a command prompt.

    Reset WINSOCK entries to installation defaults: netsh winsock reset catalog

    Reset TCP/IP stack to installation defaults. netsh int ip reset reset.log

    Reboot the machine.

    There is no non-Windows security installed. I will try uninstalling driver and letting windows find the driver.

    I had to download the driver from broadcom website as windows would not find the driver when I installed it on this computer. When I uninstall the driver from device manager and search for new hardware it reinstalls the driver automatic. I think the driver I downloaded is saved in the system32 file. I have done the winsock and tcp/ip reset previously to no avail. I will try again just to rule it out again. Any more suggestions?

    Try getting and installing the latest Broadcom driver from your PC (or motherboard) manufacturer's web site. They may have modified the "raw" driver to make it work in the system.

    Tried the driver from dell's website. Used their hardware scan to find correct driver which was actually a different, older version of the driver i had installed. Didn't work. I thought that had it! Any more suggestions?

    Should have thought of this earlier--there is a possibility of a cable defect.

    But more likely the NIC is dying; try a PCI (I'm assuming a desktop) or USB ethernet adapter.

    Driver is correct. I'll check the cable. Can you make recommendations on PCI and USB? Thanks for all your help...I wish we could have fixed it but if I can find a cheap solution that will work too.

    PCI is probably a little better (especially if using other USB devices), but USB is easier to move to another machine and can be used with laptops/netbooks.

    I downloaded Broadcom's diagnostic tool. When the internet is working it passes all tests. When it is not working and I run the Network test it asks me for a destination IP address. However, it still passes all other tests. So it seems it is losing the IP address. I have ordered a PCI and it will be here tomorrow but if the card is not the problem that may not work. Any ideas?

    I would try different cables and in a different location as well as a different port on your network switch. If all of these things fail you may need a different NIC.
