It is a Windows domain, but I manage the domain and AFAIK there is no such
policy / reset mechanism.

Oddly enough, a reboot seems to have "fixed" it, at least for now. I wonder
if the previous "fixes" were more about reboots as opposed to actual
configuration changes as well...

If it works fine, and then randomly breaks until a reboot, what might be
the cause of that?
