I have a pretty sad networking situation that involves connecting to an open Wireless network and sharing that connection to an Ethernet that is plugged into a Linksys router. This has been done with XP and Windows 7, and it works great with XP.

The problem with Windows 7 is that only some DNS will work. I don't know if it's been poisoned on the network above us (which we have no control over), but we've tried clearing the DNS cache as well as moving to using Google's DNS servers (8.8.8.8, 8.8.4.4). Here is a really quick list of sites that won't respond to DNS requests at all via dig, although if I get the IP address I can ping them:

facebook.com yuilibrary.com twitter.com

A lot of sites do work though. Anyone have an idea? It may be a subnet problem? If anyone wants more info let me know.
