Hi Matthew, Indeed but clients have their primary DNS server set to our primary, thus if our primary goes down no resolution takes place. Clients have a their seconday DNS set to our secondary DNS, but we've found that often M$ machines never even try looking at their secondary DNS server. Any ideas ?

That is, there is no need to do anything fancy - all you need to do is make sure your other nameserver is acting as a secondary for all the zones on your primary nameserver. Of course, you should really have a secondary nameserver which isn't attached to your local network - to protect against situations when you loose connectivity. Matthew.
