Ah yes, I did figure this out myself earlier today. The only question I 
have left is if there's any sort of compatibility issues I should know 
about switching a domain to using DNAME? I think I saw one post among 
the internet talking about win2k shipping out supporting the RFC behind 
this. I tried looking it up again and couldn't find it.
