I came into work today to find that 90% of my users have been locked out. I have been searching the net to see if anyone else has had this problem and they have but no one seems to know why? It look like someone is trying to login as the user and guessing the password and on my network after 3 attempts it locks the account. I have checked event logs but have found no trace...
Any help would be greatly appreciated on this.
