I've installed Wireshark onto our secondary DC, however I'm not sure whether this appliation has been installed on the correct machine. I'm assuming that by installing it on this machine, it ONLY monitors the network traffic going in/out of that particular server and that's it? am I right or is it fine to install network monitoring applications on just any server as it will pick up the entire LAN?
We have four different gateways. What's the best way for me to monitor network traffic of our entire LAN?
