Promote "PDC" in a Windows 2000 ADS in Mixed mode with many NT BDC (yet)

I have just started a migration to ADS, for now I have 4 Windows 2000 ADS as DC, and 10 NT BDC.
One of the Windows 2000 DC is a test machine and from where I started the migration (it was NT PDC before the migration)
My problem now is all the NT BDC see that "test" Server as PDC and I can't shutdown it. I tried to "promote" some of the permanent server (already as W2K DC) but it get me error.

If I shutdown the "test", all NT BDC show message "Can't find the PDC, bla bla...."

How can I configure those BDC to see another W2K DC as the PDC?

You need to transfer the PDC emulator role another windows 2000 DC I think. When you said you tried to promote a DC and it gave you an error, what did you do, and what was the error? Once a DC is a DC in windows 20000 server you can't promote it any further - the most you can do is transfer roles amongst DC's - DNS needs to be functioning correctly:
