Look at this Microsoft Support article KB917385. It seems that your AD schema has to be updated via adprep.exe /forestprep.

What roles you are transferring? From what version of server?


Do you have installed updates? Because ad is little bit changed in it.

From MS support:

To resolve this issue, run the adprep.exe /forestprep command from the Windows Server 2003 R2 installation disk 2 on the schema master. To do this, insert the Windows Server 2003 R2 installation disk 2, and then type the following command:
Drive:\CMPNENTS\R2\ADPREP\adprep.exe /forestprep

@JEREMYNO:
I just add the new server as the additional domain controller for existing domain from WIndows 2003 server.
I do not run any update or install hotfix for this server yet.

The attached file is the summary of forest when I run the ldp.exe.



@TvMpt,
You mean I need to run this command on the primary controller ?! This server located in another place.
When I try to run it on new server, the error came:
"Adprep cannot run on this platform because it is not a domain controller.
[Status/Consequence]
Adprep stopped without making any changes.
[User Action]
Run Adprep on a domain controller."

@rjanowsky,
You mean that I run this command on primary controller ?!

Yes, the adprep command must be run at a DC.
