Replication DNS between domain controllers ???

 my company has 1 dc dns, dhcp server included. primary dc.

 now, have 1 more branch office , have build 1 addtional dc.

 the addtional dc dc global catalog, doesn't has dhcp server role.

 so, when workstation join domain branch office, didn't have dns record on ad.

 how resolve , config automatic update between 2 dc ???

 thanks !!!

first of all, there no primary , secondary dc. dcs rw except rodcs.

please install dns role on new additional dc , ad-integrated zones replicated including domain zones (if still ad-integrated). once done, check zone accepting dns updates.

for client computers in second site, please make them point dns server in site primary dns server , 1 in other site secondary one.
