Windows AD setup

Hi There,

I have 1 server running AD and about 20 Windows clients, the server is running Win2k3. I have a Windows 2k8 server acting as a file server. I want to make the Win2k8 server a DC and decommission the Win2k3 for redeployment.


Is there anything special I need to do to make this work or it's just a simple addition to the domain.

Do I need to transfer the roles to the new server or it'll take them over?

Anything else I should take into account?

You will need to prepare the schema, Make sure to use correct version of ADPREP from the windows 2008 R2 CD then you can dcpromo the server
After you dcpromo Windows 2008, you will need to transfer all the roles to the new AD.

Add the AD roles to your Windows 2008 Server first.

After AD is up and running and you have two DC servers. Windows 2008 and Windows 2003

Then transfer all the FSMO roles from your Windows 2003 DC to the Windows 2008 DC.

When all that is working

Then you can Demote the Windows 2003 DC to a member server.
Mike KlineCommented:
In addition make sure your clients are pointing to the new DC for DNS (assuming you are running DNS on your current DC).  

What are you going to do with that box when you demote it.  The reason I ask is because even in a small network 2 DCs is recommended for DR scenarios.  Think if your single DC dies hard.  Have a second DC and the clients will be fine and no downtime while you fix the one that is down.
