Ok I have a couple questions for you guys.. I have a Win 2k3 Server running Exchange 2k3 that I have to monitor as well as the network.

I was wondering if there was a easy to use program for monitoring network usage by hosts on the network and can display it in graphs and such? Something that doesnt require understanding individual packets. Just want a visual representation of overall network usage as well as possible individual pcs.

Also as ive been learning Exchange 2k3 it all seems done in AD, is there any kind of program to easily monitor it? see how many messages are passing through it, and any other info that might be useful to see?

Im very new with Server 2k3 so trying to find things to help me out.. Already using Dameware NT Utilities for accessing AD and remote connecting to various pcs as needed. Wish I could be a little more specific in what type of program I need for those 2 issues but the few googles I did didnt turn up what i was looking for or think im looking for. Thanks!

I use Nagios for this. I have a server health page that has all the useful bits I need to monitor for all my servers on one page. It also supports email and pager alerts when things fail. There are a bunch of plugins to let it monitor other things located at this site.

Ill see if I cant find a way to run linux in my XP workstation and try that one out.. Thanks!
