If you already use DHCP, and you want to retain your existing DHCP database files, move the files to the new DHCP database before bringing the new DHCP server online.
Use the New Resource Wizard to create the resource.
Important
When you create a DHCP Service resource on a node, the Cluster service sets the startup type for the DHCP service on that node to Manual. The Cluster service also stops the DHCP service on all the other nodes, but, on those nodes not hosting the DHCP Service resource, the Cluster service leaves the DHCP service startup type set to Automatic. This DHCP service startup type will be set to Manual on any of the other nodes only when the DHCP Service resource fails over. In addition, if you subsequently evict a node from the cluster, the DHCP service will not be restarted on that evicted node.
