I would like to understand, in the scenario where there is One AD domain, but with several AD Sites.
in this case, Users in SiteX will always try to authenticate to domain controllers in SiteX, if all Domain Controllers in SiteX are down, then users in SiteX should be able to authenticate with other DCs in other Sites (SiteY, or SiteZ).
Well, my question is what will make users in SiteX authenticate to DCs in siteY or siteZ? is there any specific configuration that should have been done? other than associating Subnets to Sites in AD Sites and Services ?
Anyone to elaborate on this ?
