freddy, welcome on board.
I don't know how to start parsing this...
first, differences between 3.6* and 4.0* only adding functionality and speed.
if not 100% backwards compability is sure then uttleast 99,9%
to make sure your script works with kix2k1 you could run it on your own account first.
then, there is at http://home.wanadoo.nl/scripting/index.htm
kixstrip tool to check the correct syntax.
then, you are right, nt's don't need the regs and win9x neither for basic functionality but for full network info they are needed.
notice anyway that then also KIXRPC (the right version) should be used.
to easily upgrade wksta's to kix 4.02 you could go with installation softpack found on that same page.
the update on netlogon share is just replacing the exe.
if you run the kix32 from batch file, you should add the client update things in to that batch before starting kix32.exe
this way you can add routines to run kix32.exe from client and thus reduce logon time and network traffic.
don't know if I forgot something, but probably then someone will add that or you'll ask for more.
hope this helped uttleast little bit.
cheers,
