Running Windows XP Home 32bit, No network adapter will work in the computer, tried known good network adapters, but the computer will not connect to the internet. It won't even ping 127.0.0.1. Any suggestions would help. Even tried a Wirleles USB adapter.

If you excluded the NIC to be faulty, then probably it's the TCP/IP.
Try disabling any firewall you have (including windows built-in firewall) (It might be preventing ICMP protocol, so your pings time-out).
Then try to ping 127.0.0.1 again. Because this seems to be more a mis-functional TCP/IP settings.  Try resetting your TCP/IP: http://support.microsoft.com/default.aspx?kbid=299357

Tell me what happens :)
Are you also using a known good network cable and switch port? What are the DNS settings on the problem machine versus a known good configuration? Are you getting an IP address from DHCP? Try configuring a static ip.

Have you reset your TCP/IP as I told you to try? :)
It shouldn't be the settings/configurations that is causing the problem, as  your not even able to ping the localhost (127.0.0.1).. As far as I know. :)

Resetting the TCP/IP didn't work (I had high hopes), disabling the the firewall didn't work either. Any other suggestions...Plz.

Mmm.. Try running (C:\WINDOWS\network diagnostic\xpnetdiag.exe) (Network Diagnostics) .. And maybe then posting us the log, maybe we can help more :)

Commented:
That didn't help either, here's the logfile

That didn't help, Here's the log file. It would only save as an XML file and this sysem would not take it. I changed it to a txt file.

jnelson1078, it might be your last resort to reinstall your windows Don't panic :)

AFAIK, pinging 127.0.0.1 tests your TCP/IP stack It has nothing no to do with your NIC. Your NIC could be disabled from the device manager, and yet you can successfully ping 127.0.0.1 .
So having tried to re-install the TCP/IP with no luck, and making absolutely sure that there's no firewall interfering/blocking ICMP or traffic on your computer.

I would suggest trying one more time to re-install TCP/IP stack (maybe using a software this time: http://download.cnet.com/XP-TCP-IP-Repair/3000-2094_4-10410929.html)

http://www.ehow.com/how_2113298_corrupt-tcpip-stack-windows-xp.html
Try to repair your Winsock2, maybe it is corrupted as well.. (http://support.microsoft.com/kb/811259)

I can't think of any other cause to you not being able to ping 127.0.0.1 :)

I really wished I could help, I wish you have some more luck with any of the other experts here :)

ok, I ran netdiag to test the winsock. Apparently the NetBT transports test failed. It states further that there are no NetBt transports are configured.

Commented:
I got the winsock diag to pass, so I guess winsock is functioning. Attached is the log file from netdiag.

If that does not work then run an sfc /scannow command ( you will need your operating system disc to hand ) that or do a repair install after backing up your data

Forgot to mention get the latest drivers for your network cards and re install those.

Try a different port on your router / switch and a new network cable

Did all that, again, I even put a new network adapter in the computer and loaded the current drivers. No NIC works in the computer, be it wireles or wired. I repaired the the winsock several times and have ran the netdiag and it says the winsock is functioning, but it still don't work, there has to be another way other than reinstalleing nthe operating system.
I have worked on a couple of client's machines that had a similar problem. After trying MANY possible things, I decided that perhaps a Norton Firewall component was still having an effect, even though Norton had been uninstalled.

If Norton has EVER been installed on this machine, I'd recommend using the Norton Removal tool (found at this link:


http://service1.symantec.com/Support/tsgeninfo.nsf/docid/2005033108162039),

 or just google Norton Uninstaller or Norton Removal Tool

This has worked on 2 machines that I have worked on recently.

Good luck.

There were traces of old Norton files, so I ran the uninstaller. It still don't work.
Didja reboot after running the Norton uninstaller?

Commented:
Just a quick question, why is your DNS servers set to 192.168.0.1? Usually this address would be your gateway. Are you using internal or external DNS servers. This could be your problem.

Commented:
I believe without the correct DNS servers, you are not going to be able to get online or you will be able to but you won't be able to resolve the name. Did you try to get to a site by its IP address? Check that text file you attached. your DNS server says 192.168.0.1.

If you re install the norton software you had and if it has firewall software disable the firewall software and try again and if that works then run the un installer software that is mentioned above does that help ?

If not the easiest option would be to do a repair install or a fresh install
Thanks to everyone for their suggestions, but I discovered the problem. Apparently a virus was preventing any network interface adapter from functioning. After doing an external virus removal, connectivity was restored. The TCP/IP stack repairs suggesteed and winsock repairs might have been a factor, but removing the virus fixed the problem.
