Strange addresses from DHCP

Got a small Windows 08r2 domain, one DHCP server.  Lately, several of my desktops, with a wired connection, are getting a 192.168.... IP address...and the DNS suffix is showing....wait for it....."GoogleTV" instead of our domain name of CITYHIGH.LAN  (see attached shot)

Folks connecting over wifi are fine.

Wow, that makes sense.  If a GTV box is connected somewhere, wouldn't it show up in my DNS or DHCP (if it grabbed a number)?  I'm trying to find a reference to it so I can track it down and shut it down.
It would depend on whether it got a lease from your DHCP, and other settings related to DNS dynamic updates.  I assume your network is not using 192.168.1.x, but the screenshot shows 192.168.1.1 as the DHCP, so I would take that to be the Google TV.  You could do an arp command (like arp -a 192.168.0.1) to see the associated MAC address.  Depending on the capability of your switches, you could then trace the MAC to a specific port.  From there, you could unplug the cable and listen for the screams to narrow it down, or maybe your documentation would tell you where it goes from there.

The quickest solution is probably to announce publicly "We are investigating serious problems on the company network.  When we find the GoogleTV device and discover who connected it, that person will be immediately fired."
If you have DNS setup on your server then that DNS could be goofed up.

I did an arp -a to find the MAC for the 192.168.1.1 gateway.....one of my 4 year old Sony Google TV's was acting like a DHCP server.....weird.  Thanks!!!!
