Deploying new domain controller for different AD domain under the same subnet as the existing AD domain ?

people,

I have the need to deploy a separate AD domain in my data center to manage new business that requires to be joined to the comapny.

In my current setup the Data center AD sites has 2x VMs runnning as Windows Server 2008 R2 AD FFL & DFL:

Data Centre AD Sites:
PRODDC01-VM - IP: 10.1.2.8 - Schema master for Domain.com AD
PRODDC03-VM - IP: 10.1.2.10 - Domain naming master for Domain.com AD

HQ AD Sites running 1x Windows Server 2012 R2 as Physical box:
HODC01 - IP: 10.1.30.6 - Infrastructure master, PDC and RID pool manager for Domain.com AD

So my plan here is to deploy 1x new Windows Server 2012 R2 VM as new AD domain:
Data Centre AD Sites:
PRODDC04-VM - IP: 10.1.2.120 - All FSMO Role for MyNewDomain.com AD

is that going to be working with no problem or is that a big issue not according to best practice ?

from that perspective what you're proposing is not best practice

Thanks for the clarification Footech,

I was thinking that I cannot deploy domain controller for different AD domain in the same IP subnet as the current AD domain.

But yes, it is going to manage different company with different IP address anyway.

Cool, many thanks Lee.

So for the Domain Controller of a new AD domain, is it possible for me to create one way AD trust safely ?

From:

Existing: Domain.com -------into----> New: MyDomain.com
