I don't know Windows very well. This is Win XP SP3. nslookup resolves hostname fine, but ping (and other DNS-users on the machine like Chrome) cannot resolve the same hostname. ping works fine with explicit IP address.

Is this a bug in XP?

C:\>nslookup blade.haq.loc
Server:  dns.haq.loc

Name:    blade.haq.loc

C:\>ping blade.haq.loc
Ping request could not find host blade.haq.loc. Please check the name and try ag


Pinging with 32 bytes of data:

Try clearing your cache:

in cmd.exe:

ipconfig /flushdns

Try running the command:

ipconfig /flushdns

If that doesnt resolve the problem, then there could be a possible conflict with your DNS server.

So if it doesnt work,

  • Go into "Network and Sharing Center"
  • Open up the connection that you are using
  • Go to Properties
  • Look for the IPv4 Address
  • And assign it a specific DNS server, try using Google's Public DNS servers ","
