Two Domains over WAN & Firewall

-

my setup shown below, single forest, root domain , child domain, few dc's @ remote location child domain.

all fsmo roles held @ main office.

root_domain.child_domaina-----------firewall-----------child_domaina ( few dc's)

what kind of services/ports need allow between these 2 locations respect root domain controllers? note: root dc's only.

when dc's child domaina @ remote location contact root domain?

what happen when there no wan connectivity between 2 locations?

when dc's child domaina @ remote location contact root domain?

depends on dns when users parent domain login child domain machine or users child domain tries access resources in root domain. default, configuration, schema & application(if ad-integrated dns) partitions replicated between parent & child domain. if dns not been delegated root domain, users in child domain still relies on dns of parent domain name resolutions.

what happen when there no wan connectivity between 2 locations?

if users child domain or parent domain tries access shared resources in cross domain, not able neither authentication work again other domains. replication between 2 domain fail users able work fine own domain.
