You need to secure your network.

How?What should I do that this type of software should not be able to attack...

A quick search found a freeware "Anti NetCut 2 ".Try it and see if it will do what you need.HTH, JW

I have used Anti netcut and it worked on my pc. But I have more than 100 pcs in my network. How to secure the whole network. I am using Windows server 2003 and ISA server 2004 on my server and all clients get internet service from my server. How to secure the whole network? Thanks and regards

This is more of a network issue rather than a Windows issue, so what is important here is the architecture of your network. Netcut works by using ARP Spoofing. The Wikipedia article on ARP spoofing lists some defenses against this attack < http://en.wikipedia.org/wiki/ARP_spoofing >Ultimately, you need to discover which machine is generating the attack and remove them from the network. Anti-Netcut claims on their site to be able to identify the source of the attack (although I've never used this software). The routers you use can make this easy or hard as the solution will most likely boil down to using a packet-capture/display program like freewareWireshark to dump ARP packets to your screen while you disconnect legs of your network to narrow down on its source. If Anti-Netcut identifies the attacker's MAC address and you are using professional grade routers/switches, you can connect to the administrative page on your router/switch and discover which Mac Address is connected to which port and go from there. Otherwise it's hit-and-miss.HTH, JW
