STATUS_MOUNT_POINT_NOT_RESOLVED
A mount point crossed into a volume outside the active device path
STATUS_MOUNT_POINT_NOT_RESOLVED means that name resolution encountered at least one mount point whose target volume was not attached to the device object required by the create operation. The source path can be syntactically valid and the mount point can exist; the failure is in the relationship between the resolved volume and the active device stack.
This is not the same as a missing mount point or a generic drive-letter error. It often requires diagnosing volume identity, attachment state, virtual disks, redirectors, or filter/device-stack context.
Evidence that changes the answer
- Record the full input path and each mount-point transition.
- Capture the source and target volume identifiers, mount state, and device stack involved in the request.
- Check whether the operation is constrained to a particular volume or device object.
- Do not repair the path by textual substitution alone; verify the target volume's actual attachment and availability.
