[Samba] Strange Problem with Access

[Ruben Fagundo]

I would like to pose the following problem to this mailing list to see if 
any of you have any suggestions you may offer.

I am running samba on a RedHat 7.2 Athalon box with software RAID 0 dual 
IDE disks on an ext3 filesystem.

I have several users in a large community of users that are always hitting 
the samba server.  The machine has been consistently reliable with one 
exception.  There is a particularly large MS Access Database (10Meg) that 
everyone likes to use.  A problem has developed from certain Win 98 and 
Win95 computers where users get an error message saying that someone 
currently has a lock on the database, and that it cannot be 
opened.  However, smbstatus, reports that the user is actually trying to 
establish a lock on a different file, not the database in question.  To add 
to the strangeness, I have opened the database on a different computer, and 
then all of a sudden everyone else can now open it as well.  In addition to 
that, I had the database open from a win 98 machine, and someone else (that 
had been experiencing problems) opened it up, but smbstatus reports that 
the 2nd individual had a second file open in addition to the database, and 
clearly there were no other files open on that computer, by that user.  So, 
we have files opening and getting locked when they were not opened, and a 
database that only certain users can open, cause other computers are being 
told that it is already open, and locked by a different user.

Can anyone tell me what the heck is going on here, and what is the answer 
to this apparent lunacy ???

Thanks,
Ruben
