There are several copies of this file, one in the print$ share and three
on the windows client.  Permissions seem OK.

on server:
-rw-rw-r-- 1 dc2 lpadmin 48128 1999-11-05 06:32 /var/lib/samba/printers/W32X86/3/SETUP32.DLL

on client (mounted the win partition as fuse/ntfs):
-rwxrwx--- 1 dos dos 48128 2001-08-03 07:50 ./EPSON/epson10056/WIN2000/SETUP/SETUP32.DLL
-rwxrwx--- 1 dos dos 48128 1999-11-05 06:32 ./WINNT/system32/spool/drivers/w32x86/3/SETUP32.DLL
-rwxrwx--- 1 dos dos 48128 1980-06-03 08:00 ./WINNT/system32/spool/drivers/w32x86/SETUP32.DLL

Maybe the file was in use by some windows program and thus it was not
available for others.  I dont know how to check this in windows.
