samba - Mar 2005 - rpcclient adddriver command results in 'WERR_BADFILE'

I wonder if someone could help me with this problem I am getting.  I 
have been trying to get printer drivers installed onto my Samba server 
(v3.0.10 FC3) for a few days now and have finally hit this problem which 
I cannot fathom.

I run this command to copy the drivers from w32x86 into the '3'
directory:
rpcclient -U'root' -c 'adddriver "Windows NT x86" \
printer:hpz2ku07.dll:hpop1207.dat:\
hpzntp07.dll:hpocahpr.hlp:NULL:RAW:\
hpzcin06.exe,hpzscr07.dll,hpzcfg07.exe,\
hpzcoi07.dll,hpzcon07.dll,hpzeng07.exe,\
hpzflt07.dll,hpzimc07.dll,hpzime07.dll,\
hpzjui07.dll,hpzlnt07.dll,hpzpcl07.dll,\
hpzpre07.exe,hpzr3207.dll,hpzres07.dll,\
hpzrp307.dll,hpzslk07.dll,hpzsnt07.dll,\
hpzstc07.exe,hpzstw07.exe,hpztbi07.dll,\
hpztbu07.exe,hpztbx07.exe,hpzvip07.dll,\

hpop2107.dat,hpop2007.dat,hpopd907.dat,\
hpop4007.dat,hpop4107.dat,hpop6107.dat' gandalf

typing the above command results in an error displayed on the console:
result was WERR_BADFILE

and the following details in the log:

Looking at the print directory it seems to have moved 2 of the files 
into the '3' directory and some of the other files have been deleted 
(originally there were 40 files in total):

-rwxr--r--  1 root root 200704 Nov 27  2002 hpz2ku07.dll

It's strange that some of the files have been deleted, but I have no 
idea why it chokes on one of these files and reports it as bad.  I've 
tried recopying the files several times in case one of them is corrupted 
already.

Thanks
