2.2.4.36 SMB_COM_IOCTL_SECONDARY (0x28)

This command was introduced in the LAN Manager 1.0 dialect (see [SMB-LM1X] section 9.2.7). It was rendered obsolete in the NT LAN Manager dialect and is considered reserved but not implemented. Clients SHOULD NOT send requests using this command code, and servers receiving requests with this command code MUST return STATUS_NOT_IMPLEMENTED (ERRDOS/ERRbadfunc).

This command is a companion to SMB_COM_IOCTL, which has been deprecated. Please see SMB_COM_IOCTL (section 2.2.4.35) for more information.
