2003 adprep?

Last Modified: 2010-04-19
 I have one 2003 standard DC and am trying to install another2003 standard DC on the network.
I run the Active Directory role changer from the manage your server screen on the second DC and get the following:
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."

DO i run ADPREP on the first DC????
once i do that can i then run the AD install on the second DC.

Yes; run ADPREP from the second CD in the R2 set on the existing domain controller, then you should be able to promote your R2 server to a domain controller.

You need to make sure first DC is patched and up to date.  Then load second server with Windows 2003 server, patch and make sure that is up to date, then Join the second server to the domain.

Then run DCPROMO on the second server this will promote that machine to a second DC in your domain.



I tried to run adprep from the cd2 but it said it was not for this machine or something like that
could i not be running r2 on that server
how do i get it up to R2
