What OS are you using?

Can you post trace route results for this machine and for a working machine (state which is which) to a site like google? (in windows goto Start>run>cmd  then type "tracert www.google.com | c:\traced.txt"  The results will appear in a new text file called traced.txt on the root of your c: drive.

on the system you are having trouble with ,type "ipconfig /all" in the Command Prompt check to see that all the computers are on the same subnet,make sure that it has the right dns address and gateway.with out more info .like the ip address of your computers and dns and gateway.

can you ping your router? or any of the computers on the network?

if you are certain that you can connect to all other computers from the faulty computer, then the problem most probably lies in
1) If you are using NAT for sharing the connection (like Internet Connection sharing etc.) - the default gateway is set incorrectly.
Look into the network settings of the LAN card on the faulty computer and check that the gateway is set to the computer
2) If you are using a proxy : open your browser, navigate to the browser settings and check the proxy.
3) from the command prompt of hte faulty computer : ping first an external IP like this:
ping -t 64.58.79.230

and then try to ping a url:

ping -t yahoo.com

if only pinging the IP works, then the problem is in the DNS settings on hte faulty computer. open up the network settings for the lan card, and change the DNS servers to those of your ISP.

If you need more help, you will need to provide greater detail.

Are you using a firewall on the problem pc? You may need to configure it differently, or shut it down. Your router is a hw firewall of sorts, so it is redundant...

How do you have your other computers to the Internet? Do you have 1 PC sharing the Internet connection or are the 4 PCs connected to the router? Knowing how your network is connected, will help us find your glitch.

For the machine the trace is not working:

DOnno what that does but there it is!

you have no DNS address this is why you can not reslove the nameing ,and cannot access the net. you need to put your DNS in if you have one on your network..or put in your IPS DNS server in.you should be able to find this on your ISP web page or you could ipconfig on a computer you know that works on the net alright.

1. not using NAT
2. Not using firewall
3. can ping ip successfully of other comps. and router.. but cant ping ip address of a site like www.google.com
4. the DNS settings etc appear to be same as the other comps.. nothing unusual there that I see.. you can check the details in other comments where i posted the results of Ipconfig etc.

Comment to spin

the OS on faulty comp is windows ME. and the other comps have XP, and 98 OS. all other comps working fine.
the networking is fine every comp can see the rest of the comps etc..

weird man :/
If it's not pinging, let's try to get it ping first, and then worry about DNS ...

Try this with the network card from one of the other machines (if possible)
1)uninstall and reinstall everything in network settings in the ME machine. Configure a static IP address without DHCP in the same subnet. [Important] Add a proper NetBIOS name to the PC [/important]
2)Reboot and try pinging all ips inside your network, all NetBIOS names inside your network, and a buncha sites outside. Tracert as well where applicable.
3)Open Command Prompt, and then type net view \\ComputerName of all computers in your network. If you get any errors then something is screwy here.
4)if you've got a decent router try consoling to it and get it to start debugging everything and see what it says.

Also, what does the PC say when it can't ping? "Destination unreachable"?

Sorry Zumdahl....

Can we get the tracert output for the failing machine.

From what you put above I take it that the router is using address 10.18.40.1 (first hop on your working trace).  Yet you have and IP in the class C network 192.168.1.x for the host... seems a little suprising as you would need a router to get from the one network to the other.

Also noticed that the DNS servers shown on your ip configs for the working xp machine and the failing me machine are different.   Try using the same dns servers to see if this helps....

The DNS servers identical for both working and non working machine. i have checked. I donno why you thought they were different!
Also, we cant get tracert output from the failing machine. It simply says Destination unreachable.. or words to that effect.

Comment to everyone.
Here is the latest on my situation:
I noticed there was incomplete setup of Mc.Cafee virusscan and firewall a couple of days ago. SO i tried to complete the setup during that process, it was able to register me on line, go to mccafee site and download all the latest updates etc etc. So it was indeed able to go on internet. Then I thought since it kinda fixed the problem, i uninstalled it completely and restarted. now once again my internet does not work. I have completely removed every trace of it but no luck. may be i am stuck with it and i have to reinstall it so that i can connect to interent. But one thing is sure something in my registry is screwed up which created all those problems

What is the IP addresses of the working mahines? It could be that your failing machine is on a diffrent subnet.

I just realized that your internal network works,,so strike my last comment. You could probably have a problem with a firwall of some sort. Do you have any firewalls installed besides the McCaffee AV/firewall?

No other firewall. I guess when I uninstalled Mcafee firewall it didnt do a good job of uninstalling. TO make things work for now I had to install Mccafee firewall again and configure to unblock everything.
