Answer Wiki:
Hello,

A Logon Type 3 event is generated most commonly when a user logs on to a remote computer on a network for such purposes as to access a shared file or folder which is available on that computer. It can also be triggered by IIS logons if IIS is running on this computer. Have you noted any event ID #528 (successful logon) with a logon type 2 in your security logs? Logon type 2 indicates an interactive logon which occurs when a user logs on to a computer from the console.

Hope that helps!

Good luck!

Why don’t you just set the logs to overwrite events as needed?
If you right click on the log and chose properties, you can set the maximum log size larger and tell it to “Overwrite events as needed”. I you do this, the logs won’t overflow.

As was already stated, you should just set a group policy to set the security event logs on all these PCs to “overwrite events as needed”. Another option worth considering is the “prohibit logon if security log full” option- turn it off.

There’s no need to kill yourself with trying to catch people logging on and off the local PC when the domain controllers will log any logon/logoff to the domain anyways.

I would set the event log size and remote the restriction to prohibit logon if sec log is full with group policy as stated above.

You might consider getting a security event log management software like manage engine’s event log analyzer http://manageengine.adventnet.com/products/eventlog/index.html
(free for up to 5 hosts) to record all of the domain controller security logs to catch who is doing what.
