Re: DHCP Failover Solution... two servers, one pool?

Hmmm

I tell you what I do..!!! any comments please.

I have 2 domain controllers that act also as DHCP servers. All changes are
made from 1 particular DC and are replicated via a simple script, which
shuts down the service, copies the database and then starts the service
again. as there are very few changes now, we have set a schedule for this.

Our solution works because all addresses have to be reserved by MAC Address.
Therefore I can have both servers running at the same time. If one server
crashes DHCP is served by the other server which has the same reservations.

Not sure if this will work when using true DHCP where you may get a
different address each time (obviously you could get address clashes) What
you may want to do is keep the service stopped on one server, and only start
it if the primary fails.

We have been running with this for 2 years and never had a DHCP outage...
also servers exist on different geographical subnets, but the server will
only give addresses for the subnet it's on....

Not seen any third party tools, but there must be something out there.

Regards
