I have a new network with 2 Domain Controllers for redundancy.
These domain controllers run WINS which replicates and DNS which replicates with the Active Directory.
One domain controller currently runs DHCP and I wanted a way of configuring this for failover as I have with the other services.
I have read the following Microsoft article which mentions the 80/20 rule:
I do not understand how this provides failover. Why not just configure 2 DHCP servers with active scopes of half each?
I will have both DHCP servers on the same small subnet but I will be using about 75% of the addresses so if i just use 50/50 on each DHCP server if one goes down there is a possibility that not all machines could get an IP.
Has anyone set this up? and can they explain to me how it works?
