OK, if your dnsmasq server is in the 'mydomain.com' dns domain, and your 
DC was in the 'ad.mydomain.com', this would be okay. This would your 
allow your domain clients (winpc.ad.mydomain.com, for instance) to ask 
the DC for the dns data for 'another-winpc.ad.mydomain.com' and the DC 
would reply with the data. However, if 'winpc' asked for the data for 
'yetanother-winpc.mydomain.com', then the DC should realise 'I do not 
know this' and ask the dnsmasq server.
