Configure the DNS zones of the Domain (primary controllers, web pages, child domains etc) in the main Domain controller (In this Case 192.168.1.6) In DNS Request Routing put only 192.168.1.6 
 With this configuration UTM will query 192.168.1.6 for everything *.xxx.com, even to ping a comnputer in that domain pc.xxx.com. Or you can configure the second host in Definitions as Static Host

Looks like you might need to change the request routing from ad.hientn.local to just hientn.local, since hientn.local seems to be the domain name and ad.hientn.local is a specific machine inside the hientn.local domain. 
 You have now configured that the domain name is ad.hientn.local and therefore it will forward a request to ie: pcname.ad.hientn.local to the desired dc.
