Presumably in your zone file you have "$ORIGIN your.domain." (at least 
implied at the top). You are missing the trailing dot. I'll rewrite it 
using example.{com,net}:

$ORIGIN example.com.
www.example.com		IN	CNAME	www.example.net

This yields a RR named "www.example.com.example.com." which is a CNAME 
pointing to "www.example.net.example.com." The $ORIGIN value is appended 
to the name of every record which is not terminated at the root, i.e., 
has a trailing dot.

Not obvious to us. Try using real names.

$ORIGIN example.com.
www			IN	CNAME	www.example.net.

And do seek out some documentation and dead-trees. _DNS_and_BIND_ is 
highly recommended by many here, although I am not very familiar with 
it, myself.
