are you sure ?

When I was writing that stuff, I tested that case and I got the opposite
behaviour, ie the client used the spoolss pipe instead of the lanman
calls when switching between a 2.0.x release and my devel samba.

I was using an old SP at that time, maybe sp2 or sp3. They can have
changed the behaviour in newer SP. 

Never expect everything to still work after applying an SP :-) :-) :-)
