[Remote Desktop trying to connect to WAN IP]

Is there a way to receive notifications when someone logs into the computer (using Remote Desktop) that I'm running PC Monitor on?? I want to know when and if someone logs in using remote desktop.

Hello, I am trying to monitor temperatures of a Dell Poweredge 2850 Server running Windows Server 2008 R2 Standard and Poweredge 1550 Server running Windows Server 2008 Standard. Both result in not showing any hardware so I am unable to monitor temps. Is there something I can do to get this to work.
