[Samba] Win7 clients problem after upgrading samba file server to 4.12 on Arch

@Rowland,
Installing and changing to LTS kernel 5.4.38-1-lts doesn't help.
Downgrading samba and smbclient to 4.11.3 DOES help.

@Andrew, let me first clean up with kernel/samba versions, set log level to
10 and log limit to 0, delete all logs and repeat the whole exercise.
Please advice how to get a network capture, I am not that expert...

Regards, Pawel.

Our standard advise on network packet capture is here:

https://wiki.samba.org/index.php/Capture_Packets

Finally, as you are on a rolling distro, can you try Samba master, if
only for giggles?

[Samba] Win7 clients problem after upgrading samba file server to 4.12 on Arch

@Andrew,

Samba master - what do you mean? A clean compile and install from genuine
samba.org sources? As a matter of fact, I was thinking about it....

Let me do the tests now, with tcpdump. Will send some logs and outputs
later on.

You've asked previously - this is the smbstatus, already on the latest
kernel/samba versions.
The problem is persistent, no wonder...

[root at arch1 /]# LC_ALL=C smbstatus
