samba - Jan 2007 - What Happened to my SAMBA? Permissions Issue

OK. Everything is going great for 4 years on my FC3 Samba Version 3.0.3-5. 

Now all of a sudden, when someone opens a Word/Excel file on a Samba share, it
changes the user Owner to that user as well as modifies the permissions to r-x
and leaves the group/permission bits/owner setting alone.

I have the root directories for all shares with the u and g sticky bits set on,
but it is not enforcing the User sticky bit, only the Group.

HELP!

What about using some of the following (example) directives?  These can 
be defined per share:
----
force create mode = 664
create mask = 664
force directory mode = 2775
directory mask = 2775
force security mode = 664
security mask = 664
force directory security mode = 2775
directory security mask = 2775

I'd be real surprised if this happened all on its own. The question to 
ask is, what changed? What was just updated on the server? Or on the 
Clients? The answer should lead you to the solution...

OK. Here is what the Directory should and does look like prior to my opening the
file:

-rwsrws---+ 1 root AVMAX+Domain Admins 195584 Jan 25 13:29 BAe146 Access
Panels.xls

Here is what the diretory looks like after I open this file via Windows XP and
MS Excel:

-rwxrwx---+ 1 AVMAX+tbullock AVMAX+Domain Admins 195584 Jan 25 13:39 BAe146
Access Panels.xls

Here is how the share is set up in smb.conf: 

[Foyer] 
comment = Avmax Foyer Share 
browseable = yes 
writable = yes 
read only = no 
# valid users = AVMAX+TBullock 
force create mode = 0660 
force directory mode = 0770 
path = /usr/avmax_shares/Foyer 

Here is how this problem is fixed in the User Guide: 

Question: ?When user B saves a word document that is owned by user A, the
updated file is now owned by user B. Why is Samba doing this? How do I fix
this??

Answer: 
.... 
There is a workaround to solve the permissions problem. It involves
understanding how you can manage file system behavior from within the smb.conf
file, as well as understanding how UNIX file systems work. Set on the directory
in which you are changing Word documents: chmod g+s `directory_name'. This
ensures that all files will be created with the group that owns the directory.
In smb.conf share declaration section set:

force create mode = 0660 
force directory mode = 0770 

These two settings will ensure that all directories and files that get created
in the share will be readable/writable by the owner and group set on the
directory itself.

What is wrong here?

You're sure there were no new Windows Critical Updates or MS Office 
updates that might have been applied automatically that might have done 
something?

Sorry, but it just doesn't make sense that something can work for 
months, then stop working, with NOTHING changing. Maybe even some file 
corruption somewhere? Have you checked all of the filesystems on the 
Samba server?

Anyway, good luck with this, and sorry I couldn't be more help...
