Monitor network connectivity

At work I have a couple PC's that operate on a mini LAN. Static IPs. One machine operates an OPC server and the other pulls data from it via a proxy program on the server machine.

I am getting periodic dropouts of the OPC data and I have limited means to diagnose where the issue is:

- OPC server itself
- OPC to proxy program
- machine interconnectivity (which goes through a switch BTW)
- etc

If I could have a program that basically continually monitored the connection between the machines, it would give me a better idea on how to attack the problem.

Both machines are Win7 btw.

If this were me I'd use wireshark to monitor the traffic between the boxes. If you can't determine from that, install something like Nagios or Xymon on a 3rd box and agents on the two others and you'll see RAM/CPU/interface stats etc graphed out

I know Spiceworks has a free Network Monitoring tool, though I haven't used it myself. They also have a lot of smart dudes that write little custom apps/scripts to integrate into the spiceworks software. Might check them out.

Nearly every problem and atrocity in the world boils down to someone's pursuit of imaginary things (religion, borders, money). Do away with these and humanity might have a chance.
