Every good Active Directory Domain Services implementation started with sizing Domain Controllers appropriately for the environment in which they needed to be able to service clients for a period of four to five years. For years, we’ve been using adsizer.exe, a part of the Windows 2000 Resource Kit for this purpose.

Since Windows Server 2008, Microsoft no longer offers the ability to restart a Domain Controller in Directory Services Restore Mode (DSRM) from the default F8 boot menu.
Since Windows Vista, Microsoft has bundled and enabled IPv6 by default. This means Windows Vista, Windows 7 Windows Server 2008, Windows Server 2008 R2 (and all their derivate SKUs like Small Business Server) out of the box talk IPv6.
