I'm an smb newbie, but have found this document useful:

Not much about this particular subcommand:
NT_TRANSACT_IOCTL
  This command allows device and file system control functions to be 
transferred transparently from client to server.

BOOLEAN IsFsctl;                        Indicates whether the command is a
