We have 3 remote sites. At present, each has a DC, separate domain, separate internet, separate pretty much everything.We need to 'connect' these three sites, referred to as A,B and C. The plan is to have DC's at Site A, one domain, with a VPN working between all three sites.Sites A, B & C will all have their own SIMS servers.Is this how you would do it?My idea would be to have a DC at each of the sites, with a VPN connecting all three. The reasoning being that if Site A goes offline, the other two sites can carry on. If we have everything DC related at Site A only, and Site A goes offline, B & C are both going to experience issues.Thoughts please.
