“When this error is generated, it is due to the following hotfix NOT being installed onto the client machine that you are migrating into the Windows 2008 domain:

944043 Description of the Windows Server 2008 read-only domain controller compatibility pack for Windows Server 2003 clients and for Windows XP clients and for Windows Vista;EN-US;944043
