2. Type: ntdsutil
3. At the ntdsutil command prompt, type:
domain management
4. At the domain management command prompt, type:

5. At the server connections command prompt, type:
connect to server ServerName
6. At the server connections command prompt, type:

7. At the domain management command prompt, do one of the following:
• To create an application directory partition, type:

• To delete an application directory partition, type:
delete nc ApplicationDirectoryPartition
* partition management
Manages directory partitions for Active Directory Domain Services (AD DS) or Active
Directory Lightweight Directory Services (AD LDS).
This is a subcommand of Ntdsutil and Dsmgmt. Ntdsutil and Dsmgmt are command-line
tools that are built into Windows Server 2008 and Windows Server 2008 R2.
/ partition management create nc %s1 %s2
Creates the application directory partition with distinguished name %s1, on the Active
Directory domain controller or AD LDS instance with full DNS name %s2. If you specify
“NULL” for %s2, this command uses the currently connected Active Directory domain
controller.
Use this command only with AD DS. For AD LDS, use create nc %s1 %s2 %s3.
Note:
* An application directory partition is a directory partition that is replicated only to specific
domain controllers. A domain controller that participates in the replication of a particular
application directory partition hosts a replica of that partition.
