Problem with XP connectivity

Posted on 2011-10-26

I have an XP Sp2 that has developed a problem. There is no connectivity. Going into the device manager it showed that the NIC was not working. Wouldn't let me update the driver. Looking at connections there was nothing listed so I couldn't repair it or anything else.
ipconfig just shows media disconnected.  Pinging the loopback address is sucessful.
So I figured the on-board nic had gone bad.  I disabled it in bios and installed a new PCI nic. Same thing. I reset the TCP/IP Stack and the winsock stack. Same problem.
This is a known good connection and a known good cable.

Any ideas?

    Try a repair install of XP. Make sure to use the same service pack version to repair with, e.g. XP Sp2. Also try and use the same OEM media if this is an OEM licensed system.

    Your problem may have been caused by removing some software that was chained into the IP stack. The IP stack contains the so called Layered Service Provider or LSP.

    The LSP typically handles low-level Internet-related tasks, and data is passed through a chain of these programs on its way to and from the Internet. However, due to bugs in the LSP software or deletion of the software, this chain can get broken, causing the Internet connection to become inaccessible.

    You can try various utilities to fix the LSP:

    Go back into device manager, select view drop down menu, and select show hidden devices.

    Delete any NIC drivers with yellow Bangs on them ( ! ).

    After trying various things, both logical and maybe a little odd, I decided to upgrade to SP3 from a CD copy and that solved the problem.
