Virtualization Of Dhcp And Dns

[Neven1986]

Hello, i have some questions regarding virtualization.
Is it considered best practice, to have on one of DCs 2 virtual machines, one for DNS other for DHCP for example? Is that recommended at all in production enviroment?

Thank you for answer

Hi there, I don't understand your question...

You want know if you should separate DNS and DHCP on 2 different VIRTUAL machines? Let's say Vm1 = DNS Vm2 = DHCP.

I don't understand when you write: "to have on one of DCs 2 VMs". I assume you have 2 physical DCs, and you want to install 1 VM on each one. Everything correct?

Yes, your assumption is correct. Sorry for bad explanation. Let's say I have two physical DCs, and on each one 1 VM. On one VM i have DNS running, and on other VM DHCP. is this good practice?

Your solution is correct technically speaking.

But let's make a consideration:
If one server (physical or virtual) fails, you will have a problem.

So, my suggestion is: install DNS on one VM, install another DNS (as secondary) on the other VM hosted on the other server. Your clients will have in their cfg two IPs: IP_VM1 and IP_VM2. Of course under DNS settings.

Now you have another problem, your DHCP server is not redounded. If you can, the best solution is:
Install DHCP server role on both server, on the first one you create a pool, let's say: 10.0.0.100 - 10.0.0.150 and on the other server you will set 10.0.0.200 - 10.0.0.250. Doing this you are a bit more sure, because of in case of a problem on the first server, there's still the other one ready to go.

Let me know.
