Two DHCP Servers

krustykobb · 19 Dec 2013 at 20:13

Hi,

I want to have two DHCP servers on my home network for my Windows Server, however I only want to have certain machines running on one of them. How is this possible to do? I would set a scope on the server (e.g 192.168.0.100 - 192.168.0.254) and the other users use the built in router dhcp server (192.168.0.2 - 192.168.0.99).

Any help is appreciated

For the scenario described I can't see any obvious way it could work.

What are you actually trying to accomplish with this? Some additional background could help with an answer.

Two NICs and subnet?

I would like to be able to use Windows Deployment Services on Server 2012 but to do so you require a DHCP server, but I wouldn't want to keep the server on all of the time so that means I would have to leave on the router's built in DHCP server to give out IP addresses when the server isn't on, and when I want to use Windows Deployment Services I would turn it on and make it have an allow and block list to only allow the machines I want to install Windows 7 on to on to the DHCP server. I hope this helps.

Usualy you would do this over differnt switches / VLANS.
Only way I can see this working in a home enviroment is to give everything a reservation by MAC address on each DHCP scope.
However thats probbly not very practical.

You could have used virtual machines rather than physical hardware then what you could have done is set them so they only communicate locally in the VM rather than live on the network.

I've already done this in a VM - I want to implement the system I described in a previous post to my home network

Only way to do what you want is to physicaly segrigate the two networks either with two switches or a single switch with Vlans.

Would a method like this work?

You could create an "allow" filter for your Win Server (that only allowed your handful of machines), and a "deny" filter on your router (which would allow all machines but the ones specified)

That's the thing your not supposed to have two DHCP servers on one network.....
