I have recent re-installed the primary domain controller. We have another domain controller which has all the old settings on, but now I need to get it to rejoin to replicate the settings from the new pdc, how can i do this?

you need to run dcpromo on your old machine and demote it completely

you should then clean the metadat using ntdsutil

you can then promote as an additional domain controller in your new domain

I cannot run the dcpromo tool, even if i tell it that it is the last domain controller. I get error messages:

The domain controller could not be contacted, if either cannot be contacted or does not exist.

If I tell it that it is the last DC, I get:

It is not the last domain controller and the serve in unwilling to process the request.
