"A custom application directory partition can be created with a Dnscmd command or by using Ntdsutil in Windows Server 2008 and above. In Windows Server 2003, only the Ntdsutil method can be used. (You can also use the ADSI Edit utility or LDP.exe to create an application directory partition, but the methods here are more user-friendly.) To create an application directory partition using Dnscmd, perform the following steps: On a DNS server (or a domain member with the Remote Server Administration Tools pack installed), open an elevated command prompt. Type the following command: dnscmd /CreateDirectoryPartition and press Enter. : The name or IP address of the DC on which the partition will be created. Use a period (.) to specify the local server. : The DNS fully qualified domain name (FQDN) of the partition. This FQDN will determine where in Active Directory the partition will reside. Custom application directory partitions can reside within domains, within other directory partitions, or as separate trees in an Active Directory forest. To create an application directory partition using Ntdsutil, perform the following steps: Note: An application partition created using this method will not be registered in DNS immediately. Therefore, it will not be visible in the DNS console, and dnscmd commands targeted at it will return "DNS_ERROR_DP_DOES_NOT_EXIST" errors until its DNS registration is complete. Registration will typically occur within several minutes. On a DC (or a domain member with the Remote Server Administration Tools pack installed), open an elevated command prompt. Type ntdsutil. At the Ntdsutil prompt, type domain management in Windows Server 2003 or partition management in later versions. At the Domain management or Partition management prompt, type connections. At the Connections prompt, type connect to server . : the name of a DC in the domain. This does not have to be the DC on which the directory partition will be created. Type quit once to exit the Connections prompt. Type create nc . : The distinguished name (DN) of the application directory partition. This DN will determine where in Active Directory the partition will reside. Example: A partition named DC=TestPartition,DC=mydomain,DC=com will have the common name TestPartition and reside inside the mydomain.com domain. : The DNS FQDN of the DC on which the partition will be created. Type quit at each prompt until you have exited Ntdsutil." https://www.dell.com/support/article/us/en/19/sln288363/how-to-create-a-custom-application-directory-partition-in-active-directory?lang=en
