It traces back to google's server (iad04s01-in-f147.1e100.net).... Has anybody else ever gotten anything like this? What's weird is that it happened every 30 minutes or so, on the dot, and I'm behind my NAT enabled router.....

Edit - Mods, move it.... my bad, wrong area.

Haven't seen it - I'd look for something running on 192.168.1.93, maybe it's a keep-alive method ... ?

See if you can capture one of the packets that are triggering the "DNS spoof" message, it may indicate what the app is connecting to

Negative, 192.168.1.93 is my laptop. I have my system really locked down and it wasn't nothing like that. But for now, I haven't seen it happen since. Thanks man.

Way to dig up my thread... LOL

Is 8.8.8.8 a real IP on your end? Did you trace it and come up with a hostname?
