My question requires a little explanation then hopefully someone can help me.
WE have 2 Domain Controllers here. DC and DC1
DC is the RID, Schema and Operations Master. DC1 is the replica that we would like to make the failover available on.
On DC here is the part that I am unsure about.
The DC IP is
10.0.0.122 - Firewall
Now here is where things get crazy because apparently we had run out of IP's before my time, so someone configured rollover on the same DC to be
10.0.100.1 - 254
10.0.101.1 - 254
10.0.102.1 - 254
10.0.103.1 - 254
WE do not have a router so I dont understand how this works?
On the weekend we copied the DHCP database over to DC1. We then shut down DC, and we couldn't log in.
We then split the IP range on DC to 10.0.0.1-10.0.0.100 and on DC1 to 10.0.0.101-254
My 2 questions are this.
How is it that multple scopes with different subnets exists without a router
How can I setup the failover to happen?
b) How can I setup another subnet to be the failover i.e. DC1 Fails everyone to 10.0.102.25
