To be able to configure Windows Server 2012 Domain Controller within Windows 2003/2008/2008R2 network we need to check if Domain Functional Level is set up at least in Windows 2003 mode. This is the lowest required Domain Functional Level allowing Windows Server 2012 Domain Controller installation. That means, Windows 2000 DCs are not supported anymore. Microsoft does not support them with cooperation with 2012 Domain Controllers. It’s time to forget about these old DCs.
We can check this in domain, where we want to install first 2012 DC. To verify that, we need to use “Active Directory Users and Computers” or “Active Directory Domains and Trusts” console.
Using “Active Directory Users and Computers” console, select your domain and click right mouse button (RMB) on it. Choose “Raise Domain Functional Level” and check that.
If you see screen like this (Windows 2003 mode), it means that you do not need to raise your Domain Functional Level. In other case you have to remove all Windows 2000 Domain Controllers or if you have no any, raise DFL to Windows 2003 mode or higher
