It should be all cifs now, (unless your distro is a bit out of date) so
it's better to have 

SAMBA_MOUNT_SHARE_PROTOCOL="cifs"

They aren't very informative error messages.

First 
Make sure you can connect to the samba share without going via NX.

eg. on the workstation . . . 
mkdir /tmp/mountpont

mount.cifs //boltzmann/downloads /tmp/mountpont -ouser=rfleming

This ensures you are set up with a password in samba 
and the share exists etc

. . . good . .

If you are using 

        /sbin/mount.cifs
        /sbin/umount.cifs

you need to set them uid to allow an ordinary user account to do the
mount.


If it still doesn't work . . . 

Rather than keep re-connecting to FreeNX, you can test samba manually,
from within your NX session, using the command ( all on one line )


/sbin/mount.cifs //boltzmann/downloads 
        /home/rfleming/MyShares/downloads 
        -ouser=rfleming,ip=127.0.0.1,port=nxagent-port

(You will need to umount it manually if it works)

where you find your nxagent-port by running . . .

        netstat -napt|grep nxagent

and looking for the :port in the 4th field for YOUR nxagent session
eg. the 4001 from

tcp        0      0 0.0.0.0:4001            0.0.0.0:*               LISTEN 
     1234/nxagent


If you 
        telnet localhost 4001 ( in this example, from within your nx 
session ) 

and the tunnel is up through to your workstation ,you should see a new
smbd start up on your workstation with the current time eg 10:11 in field 
5

ps -ef|grep smbd

root     1234       1  0 09:01 ?        00:00:00 /usr/sbin/smbd -D -s 
/etc/samba/smb.conf
root     1240  1234  0 09:01 ?        00:00:00 /usr/sbin/smbd -D -s 
/etc/samba/smb.conf
root     1250  1234  0 10:11 ?        00:00:00 /usr/sbin/smbd -D -s 
/etc/samba/smb.conf
