[SMB] NTCreateANDX quesiotn

[yang mikey]

hi, everybody
I found a interesting thing,

when I see the header of NTCreateANCX[0xA2] via Ethereal
I found the value of WORD COUNT is 42, but the position of BYTE COUNT is not
at
(offset of WORD COUNT) +  (value of  WORD COUNT) *2.

Why it happened, and How Ethereal knows  the correct position of BYTE COUNT.

thanks a lot
                                                            Mikey
