Please help with dns questionLocked
Ive got an active directory environment as follows, Site A first dc to be brought up in forest, site B is new domain in same forest, and Site C is new domain in same forest. All is working well, but had a quick dns question. Each of these 3 domain controllers are the dns servers for theirs respected sites. I thought I read awhile back that the client machines should only have 1 dns server configured, and that being the domain controller/dns server at that location. So in my setup right now, if im at site B, and Site B’s domain controller/dns server goes down, they now have no dns server. Is it ok to add a secondary dns server to client machines, maybe assign site A’s server as the secondary to these Site B client machines? Does adding that secondary dns server to the client machine cause problems? Thanks in advance to the help???
