Settings Windows DHCP server as Authoritative

[redbeard1]

I am going to be setting up a 2008 server with its main purpose to be a DHCP server to an apartment complex. Right now a Linux server is handling DHCP for the network. In the DHCP settings for the Linux server there is an option to have it announce that it is Authoritative for the scope, which helps with DHCP conflicts if someone accidentally plugs in something that is handing out DHCP also.

Is there a way to have a Windows server do the same thing, by declaring it is Authoritative for the scope. I have looked at a Windows 2000 server running DHCP and did not see such a setting.

In doing some searching the only thing I found related to Windows was for an Authoritative DNS server.

Does such a setting exist for Windows?

The reason I'm looking for an Authoritative setting, is that I've seen Windows servers stop the dhcp service when something else is also handing out dhcp. Further research I've found states that to get around this there is a registry hack to disable rogue detection.

What option on the Linux DHCP server are you talking about?

AFAIK there's no such thing as an authoritative DHCP server, clients just accept the settings received in the first reply.

Ah, I thought it did that by default but never really looked into it.

All that seems to mean is that when it gets a DHCPREQUEST packet to renew a lease that it doesn't manage it sends back a DHCPNAK instead of ignoring the request. Then the client will send a DHCPDISCOVER and get a new IP in the correct range. All that setting does is make that process a bit quicker.

A rogue DHCP server can still hand out addresses as long as it's DHCPOFFER packet makes it to the client first.
