I am not too familiar with MS hyper V. I am not sure if what my assumption/doing is correct. I will indicate step by step what I did. Please feel free to correct my mistake or foresee any potential problem which may arise in the future.
I have installed 2 PHYSICAL servers with MS Server 2012 , let's call it ServerA and ServerB. They are in a workgroup environment
On ServerA, I have installed 2 VIRTUAL machines, which is a domain controller, let's call it AD1 and an Exchange Server 2013.
After that, I joined ServerA into the domain hosted by AD1.
On Server2, I installed 2 virtual machines, which is another domain controller, let's call it AD2 and an application server.
Then I join ServerB into the domain.
Pls advice if setup like this make any sense?
