One-Machine DHCP Configuration
Initially configure only DHCP, skip the class-of-service and failover options, and revisit the setup to enable
class-of-service and policy options.
Two-Machine DHCP Configuration
Configure the first machine as a DHCP main and the second machine as a backup, with minimal backup
configuration (changing password, enabling DHCP, and selecting the backup role), and set up the first machine
with failover load balancing, optionally scheduling failover synchronization tasks.
DNS-Only Scenarios
A DNS-only configuration could be on one, two, or three machines.
One-Machine DNS Configuration
Initially configure DNS as an Auth primary, Auth secondary, or caching server.
Two-Machine DNS Configuration
Configure the first machine as an Auth DNS primary and the second machine as a secondary, or the first
machine as a main primary and the second machine as a backup primary.
Configure the first machine as an Auth DNS and the second machine as Caching DNS.
Three-Machine DNS Configuration
Configure the first machine as an Auth DNS main primary, the second machine as a backup primary, and the
third machine as a secondary server.
Configure the first machine as Auth DNS primary, the second machine as secondary, and the third machine
as Caching DNS.
