ERROR_DS_CANT_CREATE_UNDER_SCHEMA

ERROR_DS_CANT_CREATE_UNDER_SCHEMA (8510) is an Active Directory Domain Services error. The request tried to create an ordinary directory object below the schema container. The schema naming context is reserved for attributeSchema and classSchema definitions, not users, groups, computers, or application data.

What to check

Verify the target DN and create regular objects in a domain naming context or the appropriate application partition.
For schema work, use a controlled change process and verify the exact schema object type.
Remember that schema changes are forest-wide and replicate to every domain controller.
