I have a network with 100 pcs connected across 4 swicthes. Sometime the network is jammed out due to some unkown reason and then I have to troubleshoot by removing each network cable from switch. I use angry ip scanner to check if all ip’s are alive. Is there any better approach to diagnose and stablize the network. Are there are apps that can be used to check whats going on in the network. Thanks in advance for you help.
