I'm not talking about a billion people doing the same thing. It's your network, so you don't have to block. Or, it's your network, so you can. Or, it's Gadi's network, so he can (or not). Or, it's "several different big ISP's" networks, so they can block (or not). "to stop the spread of the worm they now block tcp/445." It does work. I know. I've done it. It makes some networks better netizens as they don't have the money or resources to control the outbreaks and it's a simple way to keep worms from attacking the rest of us. Do what you want it's your network. http://www.faqs.org/rfcs/rfc1001.html 5. OVERVIEW OF NetBIOS NetBIOS was designed for use by groups of PCs, sharing a broadcast medium.
