Question : Strange DNS resolution

I have Windows 2003 network with 5 remote buildings.
I have direct point to point link from my remote offices to my HQ.
HQ has my AD DNS servers.
When I ping a name of a server I sometimes get a resolution to an IP that is not on my network.

I have checked all my DNS settings and they look correct.

How do I see which DNS servers are being used (other that what is listed in IPconfig/all), I know this sounds like stupid question but I just want to make sure that the clients are using what they are told.

and how to I query a specific/different dns server and see the result?

IPConfig /all is it, however you might check the client cache:

ipconfig /displaydns

And it would be wise to check the response for the address from each of your DNS servers.

nslookup SomeName DNSServer

e.g.

nslookup www.google.com 4.2.2.4
