The Windows 2000 Domain Controller will be installed in Mixed Mode by default. To enable
Native mode, go to the following screen in the “Active Directory Domains and Trusts”
administrative tool:
Choosing Native Mode is a one-way operation – there is no going back to Mixed Mode
without a reinstall of Windows 2000 Advanced Server or restoring a back-up. This operation
is instantaneous on a small test domain, but some Microsoft documents indicate that for
larger domains the process can be quite lengthy, and replication of the Active Directory
changes to all DCs in the domain can delay completion even longer.
An interesting item that is referenced in a Microsoft Technet document indicates that a root
domain can be Mixed Mode, and a sub domain within the forest can be Native Mode.
Rudimentary testing shows this to be accurate.
