Multiple domains on single server?

I am doing a clean install of Windows Server 2003 on a new server, consolidating several small, older servers. I want to install multiple domains on the same physical server. I installed ActiveDirectory and created the forest root domain, but am having trouble creating child domains. When I run 'dcpromo', it says that this machine is already a domain controller and the only task it will let me perform is to remove the domain controller.

Afraid you cannot do that.

Each Domain must be installed on a seperate DC, a single DC cannot host more than one AD Domain.

I'm new at this so forgive the simple question - I realize that a single domain controller can only host a single domain, but I thought that you could install multiple domain controllers on a single physical server, with each domain controller hosting a different domain. I thought that on a mainframe server, you could run all of the domains for the company. Is this not true?

thanks

Sure, but you need to install a Virtual Server (either VMWare or MS Virtual Server). You then configure and install seperate Virtual machines on that Physical Server.

To simplify it.

Each Operating System can be a single Domain Controller, a Domain Controller can only host one domain, and you can only have One active Operating System per Server (which can be either Virtual or Physical).

This is a good place to start for MS Virtual Server software:

Remember that you still need to install a seperate Operating System onto each Virtual Server you add.
