We are planning the following AD topology:
The main root domain controllers and east.ourcompany.com domain controllers will exist in the same head office datacentre location:
dc1.ourcompany.com dc2.ourcompany.com dc1.east.ourcompany.com dc2.east.ourcompany.com
west.ourcompany.com will be on a different subnet (and country) all together.
Do the head office domain controllers (the root and child domain) also need to be on a seperate subnet? I assume they do, unless we provide some kind of unique netbios names (and if so any recommendations for naming the above)?
