I have been seeing this behavior on my Vista system at home. I do not have SmartFilter and have always assumed the problem was an incompatible network driver. I do not remember having the problem when I first obtained the laptop. I seem to remember the problem appearing sometime after I let Windows Update replace my network drivers. I have never really tried to trace it down. So, if you find the magic bullet, I'd be interested in hearing.

I'm talking about the really annoying 'feature' where the network stack automagically tries to determine whether a particular NIC has a route to the internet. I'm curious b/c our Pix SmartFilter plugin (now owned by McAfee) is messing with a couple of machines and breaking their ability to actually get to the internet. If I disable filtering for the machines' ip addresses there's no problem at all. With filtering enabled they completely lose their ability to get on the internet when their DHCP leases renew and you have to disable then re-enable the NICs. (SmartFilter of course says that there's no way it's related to their product...)
