Depending on how you start these for a regular local session... Possibly
you'll have to write a little wrapper script which sets the correct
environment variables.

I dont know about fluxbox and windowmaker. But KDE sessions are normally
started by a script called "startkde" and Gnome session use "gnome-session"
(both scripts are part of each standard system). 

The commercial NoMachine NX Client calls "startkde" for a KDE session and 
"gnome-session" for a Gnome session. For other session types there is the
"custom command" (which you find by selecting session type "Unix/Custom"
--> "Settings"). 

To give you an example how my NX server is tweaked may show you how you
can adapt it to your case:

 * I left "startkde" which starts my KDE-3.3.1 sessions (installed with
   YaST on SuSE-9.1

 * I replaced the original "gnome-session" script by one that in reality
   starts my current (self-compiled) KDE HEAD. This one needed some 
   tweaks in the environment variable and then calls the "other" (KDE 
   HEAD) "startkde".

Here is what is in my manipulated "gnome-session" script:

No, you don't even need a full Samba server running on the NX server.
What you need is a working "smbmnt" (not to mix up with "smbmount",
please) utility, and smbmnt must be installed setuid root.
