AD DNS

[stephan schutter]

sorry for the paranoia... It would just be too easy for a social 
engineer with the details and the company name... if it helps you to 
know where I am... we can do this in private email...

as you can see they have the same name servers and the subnet is the 
same, and the search domain is the same... how can they get a diferent 
answer from the name server?

the hq* comes from DHCP...
