Network computers exhibiting odd behavior...

[InlineFive]

All the computers on my network (xxx.xxx.xxx.1,xxx.xxx.xxx.2,xxx.xxx.xxx.3, etc.) have been trying to contact the non-existant xxx.xxx.xxx.255:138 with UDP packets to no end over the last couple of days.

What's going on here?

Thanks!

NetBIOS datagram (UDP)

Used by Windows (and services on UNIX like SAMBA). The main danger on the Internet is that by crafting special messages sent to this port, a hacker can convince Windows that their machine is "local", and can therefore bypass some of Microsoft's security settings that differentiate between "local" and "internet" zones

So can I ignore this? All the machines are on their own local network.

Bump.

By being on their own network do you mean that there is no internet access to those computers or are you meaning that your LAN is separated from the internet by a router or something similar that will differentiate between inside traffic(LAN) and outside traffic(internet)?
