[Samba] [Samba 4.0.9 | Win 7 x64 | Office 2007 x86 | Folder Redirection | Local Cache] : Word-documents, Corrupt

[Bouke J. Henstra]

Hello,

First of all I would like to thank the Samba Project Group for this state
of the art software. I would like to thank every body for helping each
other out.
Please ignore my poor English writing. It is not my native language.
Although: I do the best I can.

We use Samba for a while now. We started with version 4.0.6 and updated
each time. Now we are at version 4.0.9 and we are planning to update our
installation to version 4.1.0.

We use Samba 4 as Active Directory Domain Controller.

We also got some shares on this same Samba server. We use the share
'profiles' for the user profiles.
Everything seems to work well but sometime we got issues with
Word-documents. These files get corrupted while working for 45 minutes to
a couple of hours.

Before we decided to work with roaming profiles I read the Samba-documents
about this option. We decided to use folder redirection including local
cache (we use desktops and notebooks).

I tried a lot of things to solve this issue (with the Word-documents):
- re-installed notebook (also replaced HDD; I installed a SSD)
- tested network wiring
- ran HDD checks (server)
- tested switches
- changed smb.conf (oplocks, locks, et cetera)
- added registry key 'RoundUpWriteTimeOnSync' to client computers at boot
time
- - REG ADD HKLM\Software\Microsoft\Windows\CurrentVersion\NetCache /v
RoundUpWriteTimeOnSync /t REG_DWORD /d 00000001 /f

Maybe there is somebody who is able to help us with this issue. I have
listed our /opt/samba/etc/smb.conf file at the end.

Thanks in advance. Bouke
