Bulding a New Domain on the same subnet as old domain...
After some advice regards building a new domain.
We currently have a domain controller in and working(SBS2003).
We are looking to build a completely new domain(2008R2) whilst using the same subnet address.
I am aware that I cannot just install 2008, and start installing & setting up AD/DNS/etc without causing problems on the current DC.
What would be the best way to go about building this new domain while not affecting the network?
