Ntdsutil is the correct tool for creating, listing, and deleting custom application partitions within an Active Directory environment. This command-line utility is specifically designed for advanced management tasks related to Active Directory Domain Services (AD DS).

The capability to manage application partitions is essential for scenarios where applications or services require their own directory partitions that are separate from the default Domain Naming Context (the standard Active Directory forest structure). By using Ntdsutil, administrators can perform tasks like creating a new application partition, checking the existing partitions, and deleting those that are no longer needed.

In contrast, the other tools listed serve different purposes. Netdom is primarily focused on domain management tasks such as trust relationships and managing domain controller authentication. Diskpart is a command-line tool used for partitioning disks on Windows systems but does not interact with Active Directory at all. Active Directory Users and Computers is a graphical interface generally used for managing user accounts and organizational units, but it does not provide the capability to manage application partitions.

Thus, Ntdsutil is the appropriate choice for these specific tasks involving custom application partitions.
