Note: All servers are Windows Server 2016. All firewalls are SonicWALL. All Workstations are Windows 10 Pro with about 6 Macs thrown in.
Working with an office that has four locations all currently in workgroup configuration. We want to add a domain controller at each location but we want all four locations to be on the same domain. We will have IPSEC VPN's configured as follows (Office A is the main location):
Office B to Office A
Office C to Office A
Office D to Office A
So the domain controller at Office A will be the "main one" in that configuration as, for example, if an account is disabled at Office C, then replication would have to occur from Office C to Office A and then from Office A to Office D before the domain controller at Office D knew anything about the account being disabled.
Question: Is this a viable setup?
Question: What would be the DNS settings for each domain controller? Assume the following subnets:
Office A - 192.168.200.x
Office B - 192.168.201.x
Office C - 192.168.202.x
Office D - 192.168.203.x
