	Sorry, I had that backwards.  The bug is that the A record 
	is cached with the TTL of the CNAME.

	CNAMES and A records have distinct, often differing TTLs. 
	HOWEVER, if you are running Windows 2000, you can forget
	about this until SP2.  There is a bug in the Win2k client
	caching dns resolver where a CNAME is cached with the
	same TTL as it's corresponding A record.
