I've posted my problem at another forum but help stopped coming. I'll just copy the posts here & hopefully someone here can help?
ME:
I've just switched to a new ISP but my pc hasn't been able to connect to the internet since the switch. My housemates' computers still connect without any trouble. The router is connected to all the computers with cables, my PC detects the line & can log into my ISP's server, but if I try to connect to any website it says "server not found". My housemates have Ubuntu & Windows 7, while I have Windows XP Home v2002, Sevice Pack 3, on a Pentium Dual-Core, E5200 @ 2.50GHz PC.
OTHER:
Are any other internet services working. For example, if you are using a mail client such as Outlook Express which is standard with XP are you getting your mail? Normally if all computers are connecting though the same router and none are using a wireless connection the issue is iolated to the one XP computer which may have a bad networking card or it could be as simple as the settings in windows have failed to recognize the new ISP and need to be checked. I don't know what you mean by logging into the ISP's server??? Do you mean that it is showing as connected in the taskbar?
ME:
No other services (utorrent, dropbox, etc) I've tried works either. A popup in the taskbar notifies me that the line is detected & fine. What I meant by my ISP's server is they gave me an address (10.0.0.2) to connect to to set up the account etc. I can do that successfully, but nothing else internet related works. If I try to open a website in Google Chrome they suggest that my DNS settings or network configuration might be messed up?
OTHER:

Start ....type in ....cmd ......ENTER [ this is for XP ]

Try switching the router off - leave for 30 seconds - switch on again.
Try connecting again.
Check the ipconfig / all again.
Is the Lease Obtained and Expires date and time still exactly the same ?

Everything is still exactly the same except the Lease Obtained/Expired now says:
Lease Obtained........16 April 2012 16:26:51
Lease Expires...........16 April 2012 17:26:51
Any ideas?
