Hi. I have a BIND 8.2.3 internal DNS server authoritive for
mydomain.com (e.g.) and when I query SOA for mydomain.com it returns
additional recs like NS and A rec. but If I query a subdomain it doesnt
return the A/NS recs.
somehost /ms/user/g/goliaa 10# dig @somehost.mydomain.com. mydomain.com.
soa

I'm interested in this 'cause Win2K seems to be choking on it. I have
stub zones for _msdcs.mydomain.com, etc. and Win2K machines are querying
SOA for subdomains of mydomain.com and BIND isnt returning the
additional recs for 'em. FYI: if I query a Win2K DNS server for
subdomains of a domain it's auth for (even one that doesnt exist) it
returns the additional recs. Any response is appreciated.
