I was reading some discussions from the samba mailing list archives. I am having a problem, and I was wondering if anyone could help me. I moved our Quickbooks database from a Windows server to a Linux box with Samba2.07-3. I experience the exact same problem mentioned in the archives here by Glenn MacGregor back in September, 2000: "I have three users on quickbooks, one with win95, one with win98 and the other with nt. If someone with either 95 or 98 opens the file first the nt user can't get in, but the other 95/98 user can. If the nt user opens the file first everything is fine. Kind of weird." I determined that Windows 95,98,millenium and 2000 can share the file just fine (simultaneously). It's only Windows NT 4. I applied SP6a just to be sure. smbstatus shows RDONLY only for the NT4 machine (unless it's the first client to open the file). The non-NT4 machines show RDWR and also open up the .qbI file (must be the 2nd step). 21297 DENY_NONE RDWR NONE /usr/local/samba/business/Accounting/Zyvex2000.qbI Tue Dec 12 14:32:21 2000 21284 DENY_NONE RDWR NONE /usr/local/samba/business/Accounting/Zyvex2000.qbI Tue Dec 12 14:32:03 2000 21324 DENY_NONE RDONLY NONE /usr/local/samba/business/Accounting/Zyvex2000.qbw Tue Dec 12 14:32:40 2000 21297 DENY_NONE RDWR NONE /usr/local/samba/business/Accounting/Zyvex2000.qbw Tue Dec 12 14:32:19 2000 21284 DENY_NONE RDWR NONE /usr/local/samba/business/Accounting/Zyvex2000.qbw Tue Dec 12 14:32:07 2000 I added "oplocks = no" first under [global], then under the [share] (i stopped and restarted samba for the change to take effect). That didn't help. Any ideas? I'm wondering if this is a bug in NT4 or samba. The problem goes away if i don't use samba, or if i don't use NT4. Since this didnt happen with the windows server, then i can only assume that samba doesn't perfectly mimic smb. What would cause NT4 to lock the file as readonly (which it's not), whereas the other OS's make it RDWR? Thanks. -- Michael J.
