Redundant DHCP on Windows Server 2008 R2 domain
Posted on 2011-09-29
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?
