NetMon and intellisense
I had a lot of “problems” with creating filters in products like Ethereal. With NetMon V3 We have intellisense, just the way I like it.
When you really do not know where to start, just type a “.” and intellisense pops up (the developers have looked at what they like in Visual Studio, and implemented this in NetMon as well.
This tool is starting to rock more and more for me.
