I trimmed this a bit, but left the IP6 info in there because I didn't think
we actually had IP6 enabled on this LAN. One obvious difference is that
there is only 1 DNS server listed in the windows config. That's because I
had added 2 in ubuntu trying to get better performance.

I'd never heard of the dig command before, and both seems to have use the
8.8.8.8 nameserver. I was hoping to check each nameserver this way, but I',
not sure I'm doing it right. I looked up the command and tried using like
this dig [nameserver] [record] as in dig 8.8.4.4 crow202.org, but it still
seems to use the 8.8.8.8 nameserver.

Out of curiosity, I tried ping yahoo.com on both the windows vma and ubuntu.
The ubuntu ping time was slight better but consistently better. ???
