I have a local area network that I'd like to check network utilization on - our performance seems slow. I have a single router and a few Ethernet switches to connect my 50+ Windows PCs. TCP/IP is main protocol.

I presume I can use Network Monitor or Wireshark for this. Correct? What is the best way to insert my capture PC into the network to determine utilization?

Thank you.

If you switch is managed, you should be able to look at the network utilization on each port. Exact way to do it depends on the switch.

Similarly many routers provide network utilization on each port.

Wireshark probably not the best way to do it, as it is only looking at the point where it is connected.
