This one has my local network boys stumped. Started getting this message about three weeks ago. Happens on all my workstations attached to the network. At first it was slightly annoying, now it is very annoying. I have not changed my PW recently, I am unaware of any changes to the network recently (except MSFT updates). If I keep entering my password, it eventually allows me to log onto the network. I am not YET having those senior moments (although I have managed to forget my ATM pin recently). I can log onto my laptop with ease if it is not attached to the network. The lockout duration is 10 minutes and lockout threshold is 50 attempts..
I wonder if my user account has become corrupted. The other user of the system does not have these issues.
TIA for any thoughts.
