What does this Event Refer too, and how do I stop it?

I have a Windowns 2003 server running 2 network monitoring tools.  IpSwitch Watsup gold and HP System Insight Manager 5.1.  

On that box, I am getting the following events over and over and over in the security events log.  From what I've been able to dig up on the internet about this Event, it's simply a successful logon/logoff.  so I don't understand why it's in my event log over and over and over.
