This would depend on your computer, at the moment your files will show 
as belonging to the group 'owners', but if you restart Samba, it is 
probable they will then show as belonging  to '2011'. If this is the 
case, then you can use chown or chgrp to change the group ownership back 
to 'owners'. I am not saying this is going to be a 5 minute job 😁
