How to locate infected computer with a UTM5 or UTM10

I have worked with a number of Firewalls over the years, but the Netgear UTM Series Firewalls are not easy to work with.  After several attempts to find what computer is trying to access an infected web site I made a printout so I could easily find my way there.

Select "Content Filter" set the date back one day and select "Download" to get a copy of the data. It opens with a spreadsheet and then you can look in there to see who the offending computer is.
