I have a domain-joined test machine running W2K8 R2 with two NICs, one connected to the enterprise network, the other one to a private network with a static IP (192.168.0.1). The machine should act as a DHCP server for the other machines on the private network (not for machines on the enterprise network, though).
After adding the DHCP role, I checked that the service only has a binding to the LAN connection on the private network.
The domain controller won't allow to authorize another DHCP server, and the DHCP service throws an error when starting up (event ID 1046): http://technet.microsoft.com/en-us/library/cc726914(WS.10).aspx
My question is: is there a way to tell the DHCP service that it'll only serve a private network and therefore doesn't have to ask the DC for authorization?
