Google "unusual traffic" captcha

["Blackwood, James" <jblackwood () LAGRANGE EDU>]

We’ve been getting this off and on for the past couple of days.  I’ve seen it once before a year or two ago but it 
resolved itself.  I get that there must be something on our network that Google has decided is making automated search 
requests which is a violation of their terms of service.  

I created a port monitor on our internet firewall and looked at the traffic destined for 215.58.219.164 (www.google.com 
based on my DNS lookup) using WireShark and see, as expected, a ton of traffic but not necessarily a ton of traffic 
from a single host.  Does anyone have any pointers on what specifically to look for?

Thanks,
James
