Free Windows Network User Accounting Reviews

FWNUA allows me to keep track of users who log into computers with dynamic IP addresses. I now have a single portal to identify every system a user has been logged into and what IP address the computer has had over it's lifetime on my network. This enables me to track down users and their activites very quickly. This is something the windows secruity event logs can not do. My opinion may be bias, but this little utility has saved the day on numerous occasions. We have even had reports of companies using FWNUA as a means of employee time tracking.
