It took a while to set up but, I finally enjoyed a fun conversations with the folks at PacketTrap. They've developed a powerful but, easy to use tool for system administrators and network administrators. Watching the demonstration really brought me back in time to my days as a network consultant for DEC's network services group. The tool reminded me a great deal of DEC's EtherNIM (Ethernet Network Integrity Monitor).
At this moment, the beta is available for download at no cost. Just visit www.packettrap.com/download and have at it!
I just love simple, small tools that go right to the heart of a specific problem. I suspect after trying it, you will too
