DNS resolve order
Hello...
Network and sites:
3 sites: A, B and C.
Site A = 192.168.1.1/24 and 172.16.4.0/24
Site B= 10.0.0.0/24
Site C = 10.5.0.0/24
********************
Active Directory and DNS:
Site A has 2 DCs:
DC1 =192.168.1.1 (DNS server)
DC2 = 192.168.1.2/ 172.16.4.1 (DNS)
Site B:
RODC3 = 10.0.0.1 (DNS)
Site C:
DC4= 172.16.5.1 (DNS)
************************** ***
Site B can only access 192.169.1.x in site A but not 172.16.4.x.
the problem is, when a client try to resolve mydomain.com or dc2 sometime it is resolved to 172.16.4.1 which is not reachable from site B network.
AD replication works fine with out issue as Site A is the hub and replicate to other sites.
Is there a way to configure DNS to response to clients queries in site B from mycompany.com with 192.168.1.1 always not 172.16.4.1 ? in other words, I want all clients in site B to be able to communicate with DC1 or DC2 in 192.168.1.1 vlan.
DCs are mix of 2012 and 2012 R2.
Thanks!

Thank you guys for your answers and good ideas that provided.... I totally agree that mutli-homed DC is not a good idea and needed to be changed. is there any official document explains the issues of having multi-home DC ?
my plan to get rid of the second nic in that DC, but need to convene the management.

Thanks a lot!
access DNS of site B from Primery Domain and check the forwarder point to your primary domain ..
on Site B domain you should have the primary dns of the same domain and secondary point to your main site primary domain.
all the best
