Adding Win Server 2003 into existing W2K Domain

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.

Hi hoggiee,

You probably did the wrong version of adprep.

Is this windows 2003 R2?  If so, you will need to run adprep from the second CD

\cmpnents\R2\adprep

Hope that helps,

What does it mean to be "Always On"?

Is your cloud always on? With an Always On cloud you won't have to worry about downtime for maintenance or software application code updates, ensuring that your bottom line isn't affected.

Hi red, I have tried that and it worked perfectly! Thanks so much.  Now I have 1 Win2K DC and 1 Win 2003 DC in my domain.  One simple question before closing: The Win2K DC currently assumes the roles as schema master, RID, ...... and I am going to remove the Win2K DC from the domain.  Do I have to manually transfer these roles to the new Win2003 DC? or they will be automatically transferred when I DCPROMO the Win2K DC?

Thanks.

Personally, I'd transfer them manually to the Windows 2003 DC before the Windows 2000 DC is demoted. You know then they're actually been moved.

You can transfer them manually, and I recommend it, but the dcpromo of the old server is *supposed* to do that automagically
