Thanks Chris for your response,
I have seen now in the logs that the zone doesn't even get loaded with a
CNAME and other data error...
So, that's kind of confusing though...that basically means you can't
have the primary domain location as a CNAME ?
If that is the desired effect, how would one go about it ???
Thanks,
Tim.
