ERROR_DS_CANT_DERIVE_SPN_FOR_DELETED_DOMAIN

ERROR_DS_CANT_DERIVE_SPN_FOR_DELETED_DOMAIN (8603) is an Active Directory Domain Services error. The directory service tried to derive a Service Principal Name for a target server, but the server domain referenced by the directory has been deleted. This usually indicates stale domain-controller metadata, an abandoned domain, or a reference that survived a domain-removal operation.

What to check

  • Verify whether the referenced domain should still exist in the forest.
  • Inspect DC and partition metadata before changing SPN values.
  • Use the documented domain or DC metadata cleanup process only after confirming that the old domain or controller is permanently gone.

Useful command

setspn -L "<ComputerAccount>"
