Event ID 4625 is logged on Windows Security logs for every 30 minute but nothing in SQL Server logs

I'm using SQL Server 2008 R2.  Event ID 4625 is logged on Windows Security logs for every 30 minute but nothing is logged on SQL Server logs.

This is from the General tab of Windows Security logs:

This event is generated when a logon request fails. It is generated on the computer where access was attempted.

The Subject fields indicate the account on the local system which requested the logon. This is most commonly a service such as the Server service, or a local process such as Winlogon.exe or Services.exe.

The Logon Type field indicates the kind of logon that was requested. The most common types are 2 (interactive) and 3 (network).

The Process Information fields indicate which account and process on the system requested the logon.

The Network Information fields indicate where a remote logon request originated. Workstation name is not always available and may be left blank in some cases.

The authentication information fields provide detailed information about this specific logon request.
 - Transited services indicate which intermediate services have participated in this logon request.
 - Package name indicates which sub-protocol was used among the NTLM protocols.
 - Key length indicates the length of the generated session key. This will be 0 if no session key was requested.

Can this be related to the owner of some databases in that instance that has expired password?  However, I really doubt that since there is another sql instance which also has some databases owned by the same owner and there is nothing logged in Windows Security logs for that instance.
