I have a Windows 2000 domain. I am trying to add a new Windows Server 2003 into the existing W2K domain as additional DC. I ran DCPROMO on the Win Svr 2003 and halfway through configuring, I got the following error message:
The operation failed because:
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 information about using the 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 did ran Adprep /forestprep and Adprep /domainprep on the W2K DC prior to the above. Any ideas? For your info, my W2K DC also has Exchange Server 2000 installed on it. The reason I am doing all these stuffs is because I am trying to migrate my W2K domain to Win 2003 domain and also Exchange Server 2003.
