Short story is that I've got something on my network with 136 open. People have a history of bringing machines in and plugging them in, I'm just trying to get to the bottom of it without shutting the box down (cutting its network access off).
My other fear is that the box might be infected and sitting on my network. Is anyone aware of a particuler exploit or virus that causes this port to open? I haven't noticed a problem with any of my other machines yet.
