While working on a client’s Gateway LT2030u netbook running Windows 7, I ran into an issue resolving dns names to IP addresses. The computer had been infected with a number of malware applications, including some Trojans and a large number of adware entries in the registry. But those were all cleaned up.
Despite several attempts to clear out everything, including:
- IPCONFIG release and renew
- removing NIC adapters and rebooting
- correcting the etc/hosts file
The computer still would not resolve a simple address like www.apple.com. IPCONFIG /ALL indicated that everything was configured correctly but Windows 7 still would not resolve the dns name.
Yes, a standard PING test to a physical IP address worked fine.
