Unknown logon attempts

Ever since upgrading to Mac OS Yosemite, I've been experiencing unknown logon attempts to my work server -- the logon attempts are coming from my home computers. The work server is Windows 2008 SBS. The logon is using an incorrect password which is causing a lockout on my user account.

I have deleted the native VPN accounts thinking this might be causing the problem. But it still occurs. I installed the Sonicwall NetExtender Mac client application to connect to my work VPN because the native Mac VPN connection did not work after the upgrade to Yosemite (I understand there's a bug in the OS). However, I was observing the logon attempt behavior prior to installing NetExtender -- so I don't think it's related.

Is there a way to determine what is causing this behavior?

Alternatively, you could check your console logs for the time the log in attempt was made. There is likely a log item for the failed attempt.

Where do I find the console logs? Do I access via terminal? Or is it viewable with a text viewer?

Thanks.

Just open Console.app found in /Applications/Utilities, or use Spotlight to search for Console.

This was so easy and quick! The offending application (Calendar) popped right out when I opened the Console.app.
