i am seeing this error on 3 pcs on the network and on our server, they are coming from 1 account that has been deleted and 2 that are still on the PC's. we are on a regular workgroup network with 2012 server std. we have Changed everybody's passwords recently. No services are using any accounts with passwords we changed. i am seeing this event log every 15 minutes. There are many task's but i dont see any with the user that has been deleted or other 2 users. This has been driving me crazy and i have to disable our account lockout policy since it is locking out 2 accounts on the server side....Any help would be great!?
