Quickbooks Data Corruption with Samba...Help

I don't have strict locking on, but I just turned it on to see what will
happen. Unfortunately, when the file corrupts I have about an hour of down
time for my people (they're getting kinda pissy about being test dummies).
It is a multi-user app and 5 people should be able to access it all at the
same time.

I'm wondering if it could be something with the Win2000 machines?

Thanks for the help.

Have you tried setting strict locking = yes.  Maybe Quickbooks is not well
behaved.  It is multi-user app, right?

I am having a ton of trouble with data corruption of my quickbooks pro
2001 data.  I am having to rebuild the database about twice a week. I
have the database sitting on a server with RH7 and Samba 2.0.7. Clients
are on Win2000 and only 3 people access the file during the day, most of
the time they access it all at the same time. I put the file on one of
the Win machines for a week and never had a problem. My last attempt at
running the database on the Linux box lasted 6 hours before I had fatal
error in Quickbooks.

Here's my global:

# from localhost (
# Date: 2001/02/13 15:24:27

# Global parameters
	workgroup = NLS
	netbios name = ZEUS
	server string = Samba Server
	log file = /var/log/samba/log.%m
	max log size = 0
	socket options = TCP_NODELAY SO_RCVBUF=8192 SO_SNDBUF=8192
	os level = 65
	preferred master = Yes
	domain master = Yes
	dns proxy = No
	wins support = Yes
	veto oplock files = /*.QBW/*.qbw/*.QBI/*.qbi/

	comment = Home Directories
	writeable = Yes
	browseable = No

	comment = All Printers
	path = /var/spool/samba
	printable = Yes
	browseable = No

	path = /home/nls
	writeable = Yes
	create mask = 0777
	level2 oplocks = Yes

Here's a little more from the smb.conf:

        blocking locks = Yes
	fake oplocks = No
	locking = Yes
	oplocks = Yes
	level2 oplocks = No
	oplock contention limit = 2
	strict locking = No
	share modes = Yes
        delete veto files=No

Can someone help me? I've run out of ideas and may have to switch to a NT
server if I can't get this figured out. My CEO is starting to breath down my
neck a bit.

Let me know what other information I need to provide.

Thanks in advance.
