multiple IPs to single machine

Thank you, thank you...  The "ignore booting" lines below did the trick.  

Funny thing is though, with this line in the .conf file, there are NO ENTRIES in the dhcpdlog file
when a RAS client attempts to boot.  I do see it in the secondary dhcp server as a line:
Sep  6 13:27:52 hw1ns2 dhcpd: [ID 702911 local7.debug] DHCPDISCOVER from 00:b0:d0:41:e1:e7 via load balance to peer highwoods1

I'll watch it for a few days, but I think this is the exact solution I needed.

Thanks again,

Gosh, this one hasn't come up for a while !

It's the Remote Access Service which asks for a pile of addresses
'just in case' another machine should call up. Either disable the RAS
service on the clients, or try this :

if (substring (option dhcp-client-identifier, 1, 3) = "RAS") {
         ignore booting;

If you'd mentioned this in the first place you could have had the
answer sooner.
