AD DNS resolution Issue for specific Site

-

hello experts,
facing issue dns resolution.
have 2 sites
site a(2003 r2 dc) & site b(2008 r2 adc)
domain name is abc.co.in
, have forwardlookup zone abcl.com (mail.abcl.com/dev.abcl.com)

i able resolve host recoreds for abc.co.in & abcl.com from site a

i facing issue site b

unable resolve records for mail.abcl.com

when trying resolve using
============================================================
nslookup mail.abcl.com 192.168.0.5 (site b adc)

getting below output

address : 192.168.0.5

non autoritative answer :
name : com.co.in
address : 192.254.185.209

==============================================================
mail.abcl.com - 192.168.0.11 (actual internal record)
i want know why trying resolve external dns (192.254.185.209)
your / pointers appreciable

r udeg


is settings site b the same site in dns server properties?

did make sure udp , tcp port 53 open both ways?

did make sure resource records have been updated?

did flush cache/ scavenging happened?

did check dns forwaders , recursion?

remember if dns server fails resolve name not authoritative, cause failed recursive query. recursive queries used dns servers resolve remote names delegated other dns zones , servers.


note: if disable recursion on dns server, not able use forwarders on same server.
