DNS resolution Issue nslookup works, but web/ping doesn't

Question

I've got a computer having DNS problems with one address only, "microsoftonline.com". Ping doesnt resolve IP but nslookup does correctly. It works from other machines. It is WinXP with no proxies

I have tried google's DNS servers with no avail. Any ideas?

The ping error is "Ping request could not find host...."

Answer 1

Check your hosts file, although I don't think that's likely to be the cause.

Disable the XP firewall and test.

Try net stop dnscache then net start dnscache. This seems to do something that ipconfig /flushdns doesn't, IMX.

Delete the arp cache: netsh interface ip delete arpcache

Check your routing table: route print

Answer 2

Try flushing your DNS cache on the machine by running this from the command line:

ipconfig /flushdns
