Replicating DHCP settings across multiple servers

[John Aldrich]

I know there's a way to get multiple DHCP servers to carry
the same information without setting up the scopes on each
server individually, but I can't seem to find anything that
says HOW to get them to do it. The reason I say I know
this, is because I've seen it done -- one of the more
senior techs here where I work has done it several months
ago, and has now assigned me the task of doing it again on
a third server.

We're wanting to take one of the DHCP servers off-line
permanently, but before we do, we want to make sure that
the DHCP is up and running on a third server which will be
moving across town, and so will be geographically
separate, for redundancy purposes.

Right now our primary DHCP server is a desktop PC running
Win2k Server. I have brought up DHCP on a third server, but
it is not getting the scopes replicated from the other
servers, as I had hoped it would "automagically" do.

If anyone knows how to do this, please CC me directly on
this, as I'm about to tear my (remaining) hair out over this!
Thanks....

By the way, we're not using active directory. I think I
have found part of the problem -- the new server is showing
up as "not authorized" and when I try to authorize it, I
keep getting an error that the active directory can't be
contacted!

Hi,

You have to manually move the DHCP scopes. Here is an article that explains

Marc:
Thanks for the tip. I did as you suggested, but the changes are not
replicating between the two servers as it previously did. As an example, I
just added a couple of statically assigned DHCP leases on one server and
those changes were not replicated on the second server. We really want
redundant DHCP servers, and there has to be a way to do that, as it has
worked that way in the past.

Why are changes not replicating across the servers the way it used to? I'm
lost here... Please give me some help getting the DHCP servers to
synchronize automagically!
