Joining new server to domain

Microsoft Windows server 2008 standard

Specs: Windows 2008 Server
Hi All

I've got a domian with server A as the domain controller. I want to demote server A and join the new server B to the domain to be the domain controller.

The current users on server A must be carried over to server B.

Both server has got Windows Server 2008 Standard.

Any information will help

Run dcpromo on server B and join it to the domain. Make it a fully redundant DC within the domain. When that's done and it's replicating properly with server A, you can then move all FSMO roles and whatever data/applications you need to and decommission server A.

You would have to move DNS for sure and to be completely honest, I'm not 100% sure this would work so hopefully someone else with experience can jump in here and tell you if it's possible or not.

I'd like to point out, it would be MUCH better for your domain to leave both running in a redundant setup so if A ever fails, B picks up seamlessly. Whereas if you have a single DC and it fails...........well, you do the math......

Dns should be on both servers are either ad intergrated or primary/secondary.

both should contain the Global catalog

As CurtR says you should have a minimum of two DCs. This is a Microsoft recommendation.

Hi All, thanks for the reply's. Do you know of any website that has got some documentation that I can read up on about doing the DCPROMO and also replecating the DNS and AD?

If you promote server B to a domain controller and install DNS on it, it will all replicate automatically as part of standard AD replication, assuming you set up DNS as Active Directory Integrated which is the default.

If you then demote server A, the FSMO roles will automatically be moved to server B as part of the demotion process.

But again, you are much better off with two DCs.

If you do this, make sure you point your clients to the new DNS server, either manually or via DHCP if you are using that.
