I have 4 sites in my domain.
Out of 4, 2 sites are ghost sites which don't have any DCs. But in 2 sites I have 9 domain controllers.
My concerns are below:
1: what is ghost site and what is use of this?
2:- I have near about 30,000 users in one site than how much DCs & GCs I requiered to be placed that site as per best practise from microsoft to manage the authenication.
Also I have windows 2008 R2 OS enterprise edition with 4 Xeon X7550 2.00GHz CPU, 10 GB RAM deatils.
3:- On the 3rd site, i have lots of application authentication , so what should be best practise to placed the DCs and GCs positions.
----------
4:- Is there any tool or script through which I can run in my domain and get to know about my all forest, domains structure issue, designing issue, replication issue, authenication issue and how can correct them ?

My infrasture details are below:
Root domain.. eg. contoso.com -----> this is only parent domain and use nothing purpose..
child domain: child.contoso.com----> all the user and application authenicated in child.contoso.com domain.
