I am getting an error when I try to promote a Windows 2003 member server to a DC,
Posted on 2006-06-01
I just upgraded my Windows 2000 Domain Controller to Windows 2003 Standard Edition DC with SP1. I have a secondary DC which is still Windows 2000. I also have a Windows Server 2003 R2 member server that I want to promote to Windows 2003 DC but whenever I ran DCPROMO on this server I am getting the following error: ""The operation failed becasue: The Active Directory Installation Wizard cannot continue because the forest is not prepared for installing Windows Server 2003. Use the Adprep command-line tool to prepare both the forest and the domain. For more info about using Adprep, see Active Directory Help.
"The version of the Active Directory schema of the source forest is not compatible with the version of Active Directory on this computer.""
I have done Adprep /forestprep and /domainprep before the upgrade and when I do it again it says it has already been updated. Does anyone know the solution to this kind of problem. Thanks
