What is a good application for monitoring ALL network traffic and bandwidth utilization?

I have a Windows Server 2003 Domain with 80 Windows XP client computers, a Server 2003 PDC and a Windows Server 2003 BDC. I am running with a 100mb backbone and four 100mb switches. At certain times throughout the day some of our network database applications are running very slow. At certain times our internet speeds seem slower than usual. I am trying to determine where our bottlenecks are and what our total bandwidth utilization is.

I am looking for a Simple Application to monitor my network bandwidth utilization in a switched environment. I need a program that can run on my Windows XP PC and not only monitor my computers traffic, but ALL network traffic. It must also be able to give me EASY to understand reports and/or charts that will help me to understand my total network bandwidth utilization throughout the day.

Most of the programs I have tried only monitor my local machine and therefore do not show me the big picture of total network utilization. I would like to find a free application or at least an application that offers a fully functional trial version so that I can test it out before purchasing it.

I have tried many different programs over the last day and a half of work and nothing has met my needs. I need to determine if my database applications are creating too much network traffic or if my internet traffic is creating too much network traffic, or if it is a combination of different things a certain points throughout the day that are overwhelming my network bandwidth. I need a program that can answer these kinds of questions without me having to spend hours pouring over the data to try to interpret it. And I need an application that is easy to setup and use.

try CACTI it"s SNMP based monitoring system that can also provide graphical stats for the network utilization
its free
but you will have to run it on a linux server

This program looked promising, however the Windows installation instruction alone were over 7 pages long.

I gave the installation a try but I think it is over my head.

Question regarding your switch/router topology. How many switches do you have, and what is their model/make/IOS?

 If you only have a couple low powered switches that are full, I would recommend that you go with more adding more powerful switches and a faster backbone (1000mb/s). If you have 82ish devices on the network and you have users moving data to and from the servers AND internet usage on top of all that, your wirespeed per port will be decreased. This could be a cause of your network speed issues.

The software by Solarwinds was probably the best program I tried. I also think the UltraSniff program by GJPSoft was a worth while program to check out. Its graphing by protocol type was quick and painless to use.
