	Microsoft clients only ever remember the first IP address of the 
first nameserver they are told about, so it's not like it makes any 
difference.  If you want high availability, you have to use a layer 
four load-balancing switch (e.g., Foundry, Alteon, RadWARE, etc...) 
sitting in front of two or more nameservers, and have it distribute 
the load to the multiple back-end machines, etc....  And then you 
need two of these, with one as a hot spare and set to steal the IP 
address if the primary dies.
