Ok, I'll try to be brief on my explanation.
1. At work we have one computer with wireless internet connection.
2. A second PC is hooked to the first one trough just a cross-over cable.
3. Was working fine for a few weeks and just yesterday got some issues.
** Apparently some "malware" was found in the 1st PC, was scanned, cleaned, some startup applications unchecked **
4. After this, the 2nd PC wasn't able to connect to the internet trough the 1st one.
5. Researched some configuration over the net on how to hook it up again.
6. Connection got re-established between the 2 PCs
Now, on both PCs, some web pages like Google (which was my home page) take forever to load and at the end, it doesn't, gives a message like "Page not found", etc.
It does connect to the net, can go on several pages, but still there are issues connecting to some sites or takes forever. I checked settings, none of them are restricted, I even place them as "Allowed"
I think I noticed something when those pages were loading, something that read about "DNS error" ... I don't know. One more thing, those same pages, they can load with no problem on a different computer at the office.
But that's what's going on, if any more data needed, let me know so I can provide (I'm writing from my home PC)
Regards.

The Domain Name Server (DNS) is a 'dictionary' computer, used to look up the IP address of the website you want to use. It sounds as if the settings on the two computers that have problems have been changed or reset.
This page explains how to change them: http://www.mediacollege.com/computer/network/dns.html
First, look at the settings on the computer that is working. Write them down and change them on the two machines which are not working.

Thanks for the advice, that might have happened, specially on the 1st PC.
I have copied the DNS address from another working computer and still doesn't work, I has to be something about configuration, not hardware, as I said, I had it working for several weeks without any issues.
I'll add something else to the story, I've changed the settings to get IP and DNS addresses automatically but the outcome is even worst, it sits there obtaining address (the revolving thing around the little PC on the right bottom) and at the end it gives a weird IP address with the yellow warning sign that says "Limited or no connection"
I'll read your links to get more info.

I have conflicts (had, I should say; a switch to W7 from Vista fixed it) with my PC to laptop connection.
I open CMD as admin on the main PC (with the laptop disconnected), type in "ipconfig/release" and then "ipconfig/renew" and reboot the PC.
Then I take the laptop and make sure it's completely disconnected from the Internet. I open CMD as admin and type "netsh winsock reset," and then reboot the laptop, and then open CMD again and do the "ipconfig/release - renew" bit.
Starting from a blank slate, it finds the connection or allows you to choose without conflict. Your catalog is dumped and you're all clear.

That will be my immediate thing to do after trying the previous suggestions in case I continue with problems, thanks a lot for your input.
Both PCs involved here run WinXp, should be the same process/commands, right?

I'm assuming so.
These "fixes" are just ways to register a new IP (per the machine, not the connection) and to clear out any junk that might be causing a conflict.
They're quick and work for a lot of conflicts between PCs and laptops sharing a connection.
But refer to the other advice if you're having DNS issues. My ghetto fixes are just on-the-fly solutions I use when I'm sick of my laptop cutting out.

Thank you very much, I will check on that. Sounds like the issue revolves around the IP, DNS addresses and some other settings.
I'll let you know of the outcome, hope this takes care of it.

If NNS error occurred, that's with your network connection. The network can't find the DNS to suort the pages in opening up. So, call your internet povider and report the issue. Check the settings of your PC internet option. Check the LAN, or your using a proxy to connect to the server. Also, check the gateway of the network provider if it's working. Call for repair. Ot, may be your Windows Firewall is preventing your network to function properly.

it may be due to virus, trojans, adware or spyware scan ur computer first.

That was one of the first things I did, I noticed some spyware on the 1st PC and ran ESETNOD32 scanner, with it's updated database and took care of about three infections.
Should I run with a different software specifically for spyware?
