but if you block ports 137-139, you can't get normal windows net messages, right? or am I clueless about this...
think about what will happen if someone opens an email that exploits this 'feature' on a LAN, but instead of "net msg 127.0.0.1 'spam spam spam'" it's "net msg 255.255.255.255 'spam spam spam'", like, say, at college. fifty people check thier mail, get fifty spams, and fifty popups appear on all the schools computers hooked into the workgroup... possibly the entire LAN....
