I've setup AD single domain with child domains underneath.
I want my root DC to replicate to all 31 child domain controllers. Is it a good idea to replicate all dc's among each other or just all child dc's to root dc. Also, in one of the child domains I accidentally erased the ndts settings from the AD Sites and Services MMC. Cannot bring it back, to specify who it will be replicating to. Any clues or suggestions.
