Open & X vs. NT Create & X

I may have overlooked an easy answer to this one ( or may be caused by a
lack of understanding of the big picture ), but here goes...

After examining some netmon traces between 

	NT4 Wks       <-> NT4 PDC
	NT4 Wks       <-> Samba PDC
	NT5 Beta1 Wks <-> NT4 PDC
	NT5 Beta1 Wks <-> Samba PDC

I noticed a couple of things that I hope someone can explain.  Although
all noticed communication negotiated the "NT LM 0.12" protocol as would
be expected, the Wks <-> NT4 PDC communications used the NT_CREATE_ANDX
command to open \lsarpc on the server during joining the domain while
the Wks <-> Samba PDC trace showed the use of OPEN_ANDX to open

Can anyone explain why the difference?  Does it matter?  I have searched
the latest CIFS draft and the previous frames in the netmon traces but
didn't see anything that would show a distinction between the NT PDC and
the Samba PDC.

More questions ( and hopefully solutions as well ) later.
