In general you are best to create both SPNs for short and FQDNs, but don't worry about doing it manually, create it automatically with the cluster. First check if the cluster thinks anything is missing: isi auth ads spn check --domain=domain.com  Then fix it: isi auth ads spn check --domain=domain.com --repair --user= Then type in your password.  The user needs rights to be able to create SPNs on the machine account in question.  Hope this helps, ~Chris
