I've been able to reduce the number of failed Windows logons on a medium-sized domain network down to a few.
However, we're getting a large number of workstations reporting the same kind of what appear to be "self-generated" failures like this;
I see that lots of these occur just after 12 noon. There are generally only a few per computer. Most, but not all, are domain rather than local logons.
It would be nice to eliminate them.
But, why do they occur and how to eliminate?
