Hi Thomas,
I see these often when an active, Internet-facing FTP server is running.
Many pubsters (FTP pirates) will scan public IPs for FTP services that
respond on the default ports. When they find one, they amass attacks to try
to get in, one of which is a dictionary attack. One of the user names they
use in a dictionary attack is the common Windows administrator account. It
is actually recommended to change the administrator account name, but many
don't. No big deal, sometimes I don't either. But when you see these,
someone is knocking trying to get in. If you don't need FTP services,
disable the service or remove it in Add/Remove, Windows Components.
