Cannot extend schema to add 2012 server as domain controller on 2003 network, would love some help with this as I have been pulling my hair out trying to get this to work.
Get the error message - A previous schema extension has defined some attribute value differently than the schema extension needed for this version of Windows Server
I have run the 'hotfix' schema extension from microsoft but it did not work.
Server with FSMO roles in windows 2003 standard SP2
When I run adprep /forestprep I get this

he forest should be upgraded to Windows 2000 Service Pack 4 (SP4) or later.

I know the CN=MSSFU2x-uidNumber" entry is for Unix system, which conflicts with the schema extensions needed for Windows Server 2008. And the "msSFU-30 XXX" entries are for Windows Server system.
(side note - since i'm running 2003 32-bit, i am using 2008 32bit adprep not 2012's )
However if i try to rename these using adsiedit and try to run adprep-forestprep I get the same error
Can the MSSFU2x-XXXX entries be deleted? Has anyone else run into this problem?
