Upgrading to Active Directory Domain Services 2008

The forest and domain needs upgrading before a 2008 DC can be installed, or a 2003 DC can be upgraded.

Windows Server 2000 cannot be upgraded to 2008, but the path can be upgraded as follow 2000 --> 2003 --> 2008.

On the Windows Server 2008 disc copy the "adprep" folder to a domain controller.

Run:

adprep /FORESTPREP

adprep /DOMAINPREP

adprep /DOMAINPREP /GPPREP (Run on the infrastructure master)
