Update information needed for upgrade to be completed

In order for a certification authority (CA) upgrade to be successful, complete information must be available about the version of Windows Server 2008 and about the version of Active Directory Directory Services that are available. To obtain complete information and complete the upgrade:

  • Confirm that the domain controller has been upgraded to Windows Server 2008.
  • Confirm that the CA you are attempting to upgrade is installed on a computer running Windows Server 2003 or Windows Server 2008. You cannot upgrade a CA from a computer running Windows 2000 directly to a computer running Windows Server 2008.
  • Restart the computer and try the upgrade again.
  • If the problem persists after a restart, contact Microsoft Customer Service and Support. For more information, see https://go.microsoft.com/fwlink/?LinkId=89446.
