Just got my first article posted at Network Computing... Yippeee!! ;)
In this article I discuss the pros and cons of active versus passive site surveys. I also discuss some of the concerns I have when i see analysts using tools incorrectly and cause you to down the rabbit hole.
When I present or troubleshoot, I always get asked about this very topic.
There is no fast or hard rule, but hope you'll find my input helpful.
Let me know if this topic interests you and I'll be glad to post more info.
