Are DNS clients smart enough to try both IPs? bind8 is, probably bind9 with a different selection routine, but it appears that W2K DNS is kinda stupid about this, but there's nothing can do about it. in any case, whether your DNSs are on one subnet or two doesn't change how Internet selects which one to query. >Or is there a better solution to this? having your DNSs on different WAN links is a good technique to eliminate single point of failure. but it's simpler to do that you are making out. :)) Len
