As most people have heard by now, Comcast has been having DNS problems of late. The upshot of this for me is that I lose network connectivity for brief periods of time just about every day. This is irritating - but it's even more irritating on my Windows notebook. About 50% of the time Windows doesn't reacquire network connectivity after things go back to normal. It can see the router under those circumstances, and my Linux box can see stuff - but there's no DNS resolution on the notebook.

The thing is, I have no idea what this is - Windows, my router, the hardware in the notebook itself? Anyone else see this sort of thing and have any ideas for me?
