Remote Alert is a Windows Home Server add-in that provides remote access notification, additional security layers and remote access activity logging. Remote Alert permits WHS Administrators to monitor remote access attempts to their Windows Home Server. Any attempt to log on to the WHS via a web browser is reported in real-time using the WHS Network Health task tray icon.
And it gets even better if combined with WHSTweet, as this will alert you though a tweet or direct mail message.
