I've been playing around with OnlineEye Pro today and its Network
Traffic Monitor has been logging attempts by a Google machine (verified
by WhoIs) to access TCP ports on my home Windows XP laptop. (It's up to
the 4100's now.)

Why would a Google machine do this? I'm running Google Desktop Search
and the Google Toolbar, but this hardly seems provocative.

McAfee Firewall doesn't seem to think it's a problem, and nothing seems
to be amiss on my laptop. It's just darned annoying.
Thanks for any insights.
