I have a SBS 2003 server and an eval version of Win Server 2k3. Trying to determine how much of a fail-over the Windows Server can be. I setup the DHCP redundancy, and it works like a charm, or so I thought. Yesterday, I had to hard reset the server (don't ask) and the DHCP redundant came online like it should, but on the SBS server, this came up...

ID 1053
The DHCP/BINL service on this computer running Windows Server 2003 for Small Business Server has encountered another server on this network with IP Address, --.--.--.--, belonging to the domain: .

I know this is sbs and it doesn't want another DHCP server running, but wondering if I have to flip the role (sbs is backup) instead of the way I have it, or if there is a reg key I can change that doesn't let sbs check if another DHCP is on.

nevermind, I happened to find it.
