New random node showing as a hypen name???

All,

So I have a new random node that appears and it has no connectors and just shows up using a hypen as its name.

When I try and search the historical records to see if I can find any events from this node, nothing appears.

I will admit there is a good chance I am missing the node in my searches but I have searched by the SourceMachine, DestinationMachine,InsertionIP, DestinationIP and nothing appears.

Can anyone help me to track down where this node is coming from or the logs associated to it so I can try and track down whats going on?
