Well as you can see, it appears to be coming up as another host on the network: I did a little research and it turns out tsclient is basically a linux equivalent to windows rdp client. That being said - I don't have any of my PC's on the nework running Linux, nor have I ever used tsclient myself personally. Is there any explanation as to why this might be coming up? My initial suspicion is that perhaps some fruit cake is trying to rdp into my network or something? I do have remote access enabled on all my machines and have port 3389 forwarded on my router.
