Domain is trying to replicate with sibling child domain and root domain

i have root domain (call a) , 2 child domains (call them dev.a , services.a) (fqdn a.s.local i'm abbreviating).

dev.a single domain 2 dcs. however, if go active directory sites , services, has domains in entire forest root domain , including child domains. correct?

in addition, if repadmin /replsum, domain trying replicate services.a , (the root domain). should replicating within itself.

i've read remove additional domain controllers not needed sites , services metadata cleanup or expand these dcs sites , services, right click ntds settings , delete (which brings warning deleting metadata). however, these dcs still functional , must not decommissioned (if happens). need remove them topology - how can this?

thanks

hello,

all dcs shown in ad sites , service irrespective domain described in http://technet.microsoft.com/en-us/library/cc754697.aspx " it important distinguish between sites , domains. sites represent physical structure of network, while domains represent logical structure of organization. site objects , contents replicated domain controllers in forest, irrespective of domain or site."

" i need remove them topology - how can this?"

dcs not longer exist in domain must removed, correct. if demoted correct or removed metadata cleanup, ad sites , services manual step. keep in mind site aware services(like dfs) may run on server dc , reason machine not removed automatically ad sites , services.
