Have a friend with a relatively new Lenovo laptop using Windows XP SP3. Overnight he can't access the Internet via browsers, email or AIM. His desktop connected to the same router is working fine.

He can access the router by IP address using either IE7 or FireFox 3.5. Anything that needs a DNS server doesn't work. This does say though that he has a working connection to the router.

He's run MalWareBytes and his own McAffee software looking for bad stuff but has found nothing.

Running "ipconfig /all" from the command prompt gives exactly the same results for the laptop as his working desktop. The DNS servers are there. He can ping the DNS servers using their IP addresses. He is being assigned a proper local network address so DHCP is working on the router.

Any thoughts on where to look next to discover why the Internet applications don't seem to be able to find the DNS servers?

FWIW, my friend took his laptop to a PC shop. Their diagnosis was malware. I don't know the identity of the malware. Anyway, the shop saved his data then formatted and reloaded XP SP3.
