Thanks Thomas,
I have tried that and I appear to be getting the same result. The DHCP
server selects subnet 170 and gives the client an address from that pool
without recognizing that there is a hosts entry for that client for
subnet 169.
I must have something not quite right in the config.
Any other ideas out there?
Thanks,
Bryan
