Hi there, using an app called Net Monitor I can see around 70kB/s continuous downloading going on. Little Snitch tells me it's mDNSResponder, to something called 00000000F1d21E.local. I've disabled/enabled it, restarted the computer and also router, switched from Ethernet to wifi and back all to no avail: it comes back each time. Any ideas what might be the cause and solution? I'm on a recent MacBook Pro, 10.6.6. Thanks!
