How to correctly split DHCP on flat nework
We have two buildings connected with a fiber cable. These building work on one flat network, unfortunately. The Windows Server 2008 DHCP server is in the first building. We are trying to provide DHCP to the second building if the first building goes off-line.
I have implemented another Windows Server 2008 DHCP server in the second building and it is working ok. At this point users get IPs at random from either server.
Is there a better way to do this on a flat network?

if the connection drops, how do you propose turning on the DHCP server ?
why would you suggest not having both DHCP servers running with suitable exclusions ?

Also, as long as your second building's DHCP server is functioning correctly and you do lose connection to your first building, the clients with leases from the first building's DHCP server will be just fine (as long as you have the same scope options set on both servers, i.e. DNS servers, gateway, WINs, etc.) and when their leases are coming up to expire they will broadcast that they need a new lease at which time the second building's DHCP server will hand out leases. This is also assuming you're going to be down long enough for that to happen.

I tend to not use conflict detection, but instead to just use exclusions....
I would agree with forgetting about 80/20, use 50/50 :-)

1) Create two DHCP servers, which you've already done
2) Create/configure the scopes and options you want for them both on each server, which you've already done
3) Simply turn the DHCP service for the 2nd/backup DHCP server off until a network outtage or other event warrants turning it on. If the first building drops connection to the second or if the first DHCP server fails, turn the DHCP service on the 2nd server on and release/renew client IPs.
