Thanks for the update.

In addition, I tried running samba-tool dbcheck --cross-ncs --fix
that command generates over 400 errors that it claims it is going to fix
it does not.

(pht-vdc1 pts9) # samba-tool dbcheck --cross-ncs --fix --yes
ERROR: Failed to fix old DN string on attribute
msSBSComputerUserAccessOverride : (16, "attribute
'msSBSComputerUserAccessOverride': no matching attribute value while
deleting attribute on 'CN=Chris

I had been bitten by this part in the past, too.

The 'dbcheck --fix --yes' operation is transactional, i.e. either the whole
thing (all 400 updates) succeeds, or the whole thing fails (which is what
you are seeing) and no changes are committed.

You'll need to run without --yes, and confirm each one individually, I
think, in order to fix the 399 that are OK.

So I took your suggestion and confirmed each one individually. That got me
from 409 down to 407. :-(
I tried it twice and got the same results.

Below is a sample of the output:

Does anyone have any other ideas how to fix this? I am hoping that if I fix this it will
then let me cleanup the dead Windows DC.
