Overheard at the Office #46

A client called in and reported that their Active Directory account was locked out.  They had no idea how, they hadn't tried logging in yet today.  So I unlock the account and stay on the phone while they verify that they can get in now.  I ask one more time about how it could have got locked, and then the user suddenly puts 2 and 2 together.  They were cleaning their keyboard out, and afterwards noticed that the computer was at the login screen when they were done.
