ERROR_DS_NAMING_VIOLATION

ERROR_DS_NAMING_VIOLATION (0x00002037) is an Active Directory Domain Services LDAP result. The requested LDAP add, move, or rename violates directory naming rules.

Compare the proposed RDN, parent container, objectClass, and schema naming rules. Correct the requested directory structure at its source; changing only escaping cannot fix a name that is structurally invalid for that object type.

What to check

  • Validate the requested RDN and parent DN against the object class and naming-context rules.
  • Check for prohibited special characters, duplicate names, or attempts to move objects across naming-context boundaries.
  • Review the target container and object class before renaming production objects.

Useful command

Get-ADObject -Identity "<distinguishedName>" -Properties Name,DistinguishedName,objectClass
