Hi All,
I have a corporate network with 40 computers connected to a domain controller. It is a Windows based network. We have an ADSL router from an ISP that gives the internet connection. From the router, the connection goes to a Netscreen 5GT firewall and from there it connects to the LAN. Sometimes due to virus and other problem, few machines fire heavy traffic on the network. This causes the entire LAN speed and internet speed to drop. Since the firewall is from our Head Office, me as an Administrator doesnt have access to it. Even the ISP cant see the local computers on the router. So its very difficult to identify which computer is causing the problem or causing this high traffic.
Now i need help. I need to use some software that could tell me the LAN traffic by individual computers on my lan- either as a graph or through any figures. I need to find which computer is causing all the trouble. Now wht i do is to unplug one by one LAN cable and observe the traffic. This is really cumbersome..
Can anyone help.
Thanks in advance
Seige
