A little packet sniffing shows they are netbios name service packets.
They come from the user's IP and are sent to the Class C's broadcast
address. When this occurs, the whole network freezes for a minute or
two.
This does not appear to be a deliberate "attack" by the user. I suspect
that the wrong combination of settings on the user end causes this. Has
anyone else seen this? I have been unable to duplicate the problem so far.
Tomorrow I'll call them all and audit their settings to see if I can
see a pattern, but if you've seen this and know what's causing it please
let me know - thanks.
