I am having trouble adding a 2003 server R2 x64 machine to a 2003 sbs server R2 X86 domain as a domain controller.
I found kb919151 which seems to address the issue. I downloaded the kb to a directory c:\hotfix\adprep
In the ADPREP directory there a number of ldf files (sch14.ldf) which I assume are for the schema update and subfolders of x64, x86 which has the respective version of ADPREP.exe in them.
When I run the 32 bit ADPREP /DOMAINPREP from command prompt at c:\hotfix\adprep\x86 I get an error about needing to be run in the directory with schema.ini and sch*.ldf.
I am thinking all I would need to do is copy the x86 version to the ADPREP directory.
I just wanted confirmation from someone who may have done this update before I try it. The hotfix came with no instructions other than apply and reboot.
