Originally installed a subdomain to our domain.  The DC had the wrong bit OS installed so reinstalled os without demoting dc.

Ran the how to remove orphaned domains from active directory and succeeded in removing the domain.  I removed servers to a workgroup and the rejoined to the primary domain again.

Now I am trying to dcpromo back into subdomain but get the following error which kicks the server out of primary domain and into a workgroup.

Forest prep is not prepared for installing windows server 2003.  Use adprep command line tool to prepare both the forest and the domain.

The version of the active directory schema of the source forest is not compatible with the version of active directory on this computer.

with windows 2003 R2 (release 2) you will need to run the adprep tools from the second cd supplied in the 2 cd set!

\CMPNENTS\R2\ADPREP

you can also download here

this boosts the schema up to cope with R2 functionality

run it on the master domain controller or on the new server I am trying to promote?  Because I ran it on the new server and it gave me the same error.

needs to be done on the DC/Schema Master

I did it on the DC that holds the FSMO role and get the following:


D:\CMPNENTS\R2\ADPREP>adprep /forestprep
The image file D:\CMPNENTS\R2\ADPREP\ADPREP.EXE is valid, but is for a machine t
ype other than the current machine.

you running the 64bit CD of the 32 Bit?

Commented:
That's probably it.  I am running 32 bit of server 2003 on FSMO server and running 64 bit R2 on new server.

Can I extend on a 32 bit FSMO using 64 bit R2... probably not... then I should find 32 bit of R2 and install CD2 and run on FSMO again....  right?
