A couple of years ago I asked how to configure redundant DHCP servers.

Everyone replied that it could not be done, except for the last
with detailed (and easy) instructions on how to do it. Been running
DHCP servers on the same subnet for two years now.

The short answer is when configuring the Subnet Address Range, the
Type" MUST BE CHANGED from the default "Dynamic BootP and DHCP"
to "Dynamic DHCP". Just say no to BootP and you can set up as many
redundant DHCP servers as you like.

The thread was preserved in the Cool Solutions archive. You can check

servers see TID 10060959
