Yes, this is the only machine it's happening on. I've tried logging into other domain member
workstations as the domain admin, and no such errors/lockout occur.

Any idea what it could be? This computer has been a Samba4 domain member for about 4 years. It
is a server, no email, no network attached drives, no normal users log in except for me as the
administrator to occasionally run ADUC and also to occasionalyy run/configure Acronis backup
(which I've now deleted from the system in case that was the problem -- it wasn't); and I log
in as 'mark' to run SQL Server Management Studio. As mentioned, when I actually log in as
'mark' I have lockout consequences.
I've sent another response on this to Andrew Bartlett with kerberos logging info.
I have run, and am running now, a virus scan. So far nothing bad found.
