Multiple Domains on A Single Machine

[FanacooL]

Hi: -

I have a server machine working as PDC running windows 2003 on it. Now suppose the domain configuring in it is abc.com and now we want to change that domain to xyz.com. I have one option to remove the current domain/ remove AD and re-configuring them for xyz.com but normally it happened with me that once i remove the AD or Domain i have encounter too much problem and lastly i re-installed the windows in it. So i need your suggestion/ help that is it possible that i can do this without installing the complete OS.

Is it possible to run both the DNS abc. and xyz.com Simultaneously.

If its possible than later on i have to remove the abc.com and will that gona effect the clients or even the server too.

Domain Renaming is a serious consideration and not something you should just do on a whim. You should really do some reading on domain renaming first. I suggest starting here -

First, there has been no such thing as a PDC/BDC model since NT4 domains. Win2000 on up have global catalogs now so there is no need for a "PDC".

Just by the fact that you don't understand this basic domain concept, running parallel domains would be a terrible idea for you (but yes, it can be done). If you want to change domain names, you're going to have to re-engineer *everything*.

You can demote DCs but it isn't always a clean process. Re-installation is the best way to go.

Yes. DNS is DNS. It is not Microsoft/AD centric.

If its possible than later on i have to remove the abc.com and will that gona effect the clients or even the server too.

It depends on too many things to accurately answer this.

Bottom line: Unless it is absolutely a must, don't do it. You're asking for a world of hurt.
