[Samba] strange problems with permissions

[John Joseph Bachir]

Hello. If anyone can point me in the right direction on this problem I
would be very greatful. I was hoping there was a "newbie" list but
didn't see one. If there is a more appropriate list for this question,
please let me know.

I am running samba on linux, with mac and windows clients using two
different samba shares, one password protected and one with no
password. Once in a while, we get strange permissions problems. In
particular, a user who uses Quickbooks and keeps their data on the
server. Quickbooks often thinks that the file is in use by someone
else, and we know this is not the case. I haven't done enough testing
to see what exactly causes the problem. I suspect it is some
combination of Quickbooks being open while the computer goes to sleep
and wakes up, or changing from wired to wireless networks.

Today, everyone on the network said that they couldn't write anything
to the shares, only read. I rebooted the server and everything was
back to normal.

We will go for for extended periods with no problems, and then get
problems like this.

Below is the specs of the setup and the samba configuration. Let me
know if you would like any more details.
