This is a question for all the current Network Admins:
I read as many magzaines as I can on IT (Network Computing, Windows IT Pro, Redmond, TechNet etc...) and what I would like to ask is this:
Do any of you Admins ever use these add-on programs that are advertised or written about?  Things such as:
GFi Network Server Monitor?  NetOp Remote Control?  AD Managers? Exchange monitors? or iHateSpam for Exchange from Sunbelt Software? Etc...
I just see so many of them and was thinking how much space it would use up and how it could bog down the system...it just seems like a lot of add-ons exist to do everything for you... 

Just curious.
Thanks!
