Change Notification across AD Sites

by default, replication interval between ad sites 180 minutes minimum value = 15 minutes. of changes in domain controller notified other domain controllers in ad site following replication interval settings. hence, there 15 minutes dc replication latency among ad sites. changes in domain controllers considered “urgent replication”.

to minimize replication latency in corporate network across ad sites, requires updating attribute in ad site link accordingly in order notify domain controller in ad site when ad changes initiated , detected. can configure change notifications on connections between sites using adsiedit.msc tool.

enabling change notifications across site links propagates change notifications. change notification between sites set, changes propagate remote site same frequency propagated within source site, including changes warrant urgent replication.

enable change notifications, means change in ad no matter a urgent replication, replicate site @ near real time?

thx

i deleted post fault, said previously: can put dcs in default site if want avoid replication latency.

enabling change notifications across site links propagates change notifications. change notification between sites set, changes propagate remote site same frequency propagated within source site, including changes warrant urgent replication.

based on that, think changes replicate sites connections occur on link on enabled change notifications @ near real time.

for urgent replication:

urgent replication implemented notifying replication partners on rpc/ip changes have occurred on source domain controller. urgent replication uses regular change notification between destination , source domain controller pairs otherwise use change notification, notification sent in response urgent events instead of waiting default period of 5 minutes. therefore, if have change notification enabled on site link, urgent replication possible between sites events trigger it.
