Preparing Active Directory for Server 2008 DC’s

Note:  These steps should be completed before promoting or upgrading an existing domain controller.

• Run adprep /forestprep on the schema master of the forest.  This extends the schema to receive new 2008 features.  The changes must replicate through the forest before proceeding.
  You must be a member of the Enterprise Admins, Schema Admins, and Domain Admins in the forest root domain.
  Any Windows 2000 DC’s must be upgraded to SP2 or later, or SP1 with hotfix QFE265089.
• Run adprep /domainprep on the infrastructure master of each domain that will be accepting Server 2008 DC’s.
  It adjusts ACL’s on AD objects, and the SYSVOL shared folder.
  You must be a member of Domain Admins, and the domain’s functional level must be Windows 2000 server native or higher.
  adprep /domainprep /prep can also be run to enable resultant set of policy planning mode functionality.
