Very good...that helps me see what is actually happening. when I nslookup
heather it does in fact identify heather.earthlink.net using an earthlink
DNS machine. If I nslookup one of the other computers it uses the same
earthlink DNS machine but can't find the computer which is exactly what I'd
expect based on this and previous answers.
Many thanks for helping me understand a bit more of the wonderful world of
networks.
