So, in the past with ISA you could set up a query for a machine and then watch the traffic for just that machine.
This was helpful as i'm using a white list and someone will ask for a site with other CDN sites that i need to open as well e.g. (hotmail.com may also need live.com, and microsoft.com etc.).
There is the "Activity" section under Monitoring but it's hard to watch for denied URL's when you have hundreds of users browsing and the list is jumping all around. Is there a better place to show just denied connections for a particular user? and if not what are people using to do this?
