What are the best server auditing/monitoring tools to track changes, check traffic, etc.?

What are the best tools to monitor inbound/outbound traffic on a Windows 2003 web server?  What about a tool that tracks changes to files including the username of the last 10 people to modify? What about a tool that notifies the webmaster when hack attempts are suspected? In short, I need tools that will report the status of my web server.
