Redundant DHCP on Windows Server 2008 R2 domain

Hi

I have a domain controller and a backup domain controller on my Windows Server 2008 R2 domain, the PDC is configured to do DNS and DHCP.

The backup domain controller is set to do DNS but not DHCP.

On the DHCP server, I have reservations for key machines on our network, which undertake specific activities.

It's my understanding that DHCP servers can't co-exist nicely, and that if I set up the second machine as DHCP as well, there may be clashes?

Ideally I'd like a transparent redundancy, where if the PDC is down the BDC takes on the DHCP role, using the same reservations. Is this possible?

Can anyone advise please?

Actually, now 2008 R2 has great improvement in DHCP area :)
You can configure 2 DHCP server in co-existance using DHCP Split Scope wizard. Check this step-by-step MS article about that and enjoy with new feature :]

and just to inform :) Do not use PDC,BDC it's no longer in use ;) DCs are working now in multi-master replication topology so there is no PDC or BDC. The only one difference is that FSMO roles holder

brilliant! And it looks like it shares the reservations too!

Thanks
