Here my configuration
3 DCs servers
Server1, Windows 2012 R2, DNS, DHCP, DC with 4 FSMO roles
Server2, Windows 2008 R2, DNS, DC
Server3, Windows 2008 R2, DNS, DC
IP config of the 3 servers is as follow :
Server1 : DNS1 = Server1, DNS2 = Server2
Server2 : DNS1 = Server2, DNS2 = Server3
Server3 : DNS1 = Server3, DNS2 = Server1
Sometimes it happens that for internal reasons we have to shut down all 3 servers for many hours.
My problem is that I do have problem for restarting DNS on servers when turning them on.
The DNS Service starts OK but DNS configuration is not retreaved and it asks me to to create a new DNS server of something like that
My questions :
Is my DNS IP configuration correct ?
When all 3 servers have been shut down, Is there « an order » to turn on servers, one after the other, or all 3 at the same time ?
Is there a way to retreive DNS config and not playing with IP DNS addressing ?
