I have a Forest A with child domains B and C.
DNS is configured with A.com and within A.com the domain B and C are listed. Server b1 is in the b.a.com domain. I have a DNS host(A) entry for b1 in A.com and I have a host(A) entry for b1 in b.a.com. From the forest root A.com DC I ping b1 - and I get a ping response of b1.a.com - the problem is this server (b1) is part of the b.a.com domain - should the ping not be b1.b.a.com?

Based on what you provided, the DNS server for A.com knows where server b1 is located directly because there is a host record for b1 in DNS for A.com.

If you remove this record, it may have to query the DNS server in b.a.com to locate server b1.
