There's 2 machines, Windows 10 (192.168.1.2 and 192.168.1.3
it have 2 Ethernet ports) with share Data$
And Arch Linux which mounts that share and who also have nmbd,
winbindd and smbd running with several shares
[global]
server string = Server
workgroup = WORK
domain master = Yes
preferred master = Yes
log file = /var/log/samba/%m.log
max log size = 2000
printcap name = /etc/printcap
name resolve order = host lmhosts wins bcast
time server = Yes
unix extensions = No
security = USER
dns proxy = No
idmap config * : backend = tdb
store dos attributes = Yes
map acl inherit = Yes
hosts allow = 192.168.0. 192.168.1. 127.
inherit acls = Yes
inherit permissions = Yes
vfs objects = streams_xattr
[Share$]
comment = Share
path = /mnt/Share
wide links = Yes
create mask = 0760
directory mask = 0750
read only = No
valid users = @Share
and so on similar shares.
In Windows 10 then these shares are mapped as drive letters.
So basically both PCs does access and use each other shares in same
time.
There actually are other Windows machines too which also use
these shares and that Windows 10 share but I don't consider them
important for this issue.
Another backtrace is a bit different, but still looks about same:
