Had (2) 2003 DC's, Updated the primary to 2008 32 bit , ran DCpromo /forestprep and /domainprep without incident.
While updating the secondary machine I had some sort of corruption occur rendering the machine unbootable but otherwise intact. End result was that the machine was not DCpromo-ed out of the system.
Installed 2008 R2 64 bit on this machine, installation went fine.
Tried to DCPromo to a DC and DNS and it fails saying I need to run DCpromo /forestprep and /domainprep again. I learn that 2008 R2 had its own ADprep32 for use on a 32 bit existing DC so I copy that to my qorkign DC and run it. There is no feedback but it returns opt the cmd prompt without error
Still cant promote this second machine, same error.
On the working machine:
ADSIedit shows objectversion at 44 and ADupdate at revision 3 both indicating schema is at server 2008 not R2. Since the working server is indeed 2008 and not R2 I thought that was OK.
I am at a 2008 functional level
DCPromo continues to fail on the new R2 machine and I am out of ideas. I have gone through and cleaned out all the metadata of the old machine I could find.
What else can I try?
