I'm receiving the following Event 4625 Audit Failure every few seconds on a Server 2012 Essentials Domain Controller. I'm hoping someone might have an idea as to what's causing this. I do have a SQL Server and Windows Internal Database installed on the server but that's it.
An account failed to log on.
