Configuring HA DHCP on Windows Server 2012 Without Clustering

Server 2012 has brought a much welcomed improvement to the DHCP Server role. You can now do lease replication for highly available DHCP without needing to do clustering or split-scope. This is beneficial, because you don't need to add the complexity of a failover cluster or the ugliness of split-scope to have multiple DHCP servers provide IP addresses for a given scope.
