STATUSOBJECTNAMENOTFOUND

STATUS_OBJECT_NAME_NOT_FOUND is a Windows NTSTATUS error code indicating that a named object could not be found in the Windows Object Manager namespace. It is part of the NTSTATUS set used by the Windows kernel and many subsystems to report the result of operations. The numeric value of this status is 0xC0000034.

Meaning and scope: The code is returned when an operation attempts to locate or open a named object and the object does not exist. Named objects can include files, directories, registry keys, symbolic links, events, semaphores, devices, or other kernel objects. The object manager is responsible for resolving object names within its namespace, and failure to find a matching name yields this status.

Contexts and usage: STATUS_OBJECT_NAME_NOT_FOUND can be produced by native system calls such as NtOpenFile, NtOpenEvent, or other Nt*Open functions when the specified object name is invalid or does not correspond to any existing object. It may also arise in kernel-mode drivers or low-level components that construct object names for access in the object namespace or in certain registry or device-related operations. In user-mode applications using the Win32 API, the equivalent failures are often reported as ERROR_FILE_NOT_FOUND or ERROR_PATH_NOT_FOUND, depending on the operation and the API boundary.

Resolution and interpretation: When this status is encountered, the typical steps are to verify that the object name and path are correct, confirm that the target object exists, and ensure that the caller has appropriate access to the correct namespace. If the object has been moved or deleted, updating the reference to the new name or recreating the object may be necessary.
