Have you tried Netdiag and analyzed the results? Sorry not to have
mentioned that before.

On the already working domain controller, dcdiag is additionally useful
(netdiag and dcdiag there). On the server that won't promote, netdiag is
the tool.

You also want to make sure that they share the same name servers. The
promoted DC should be using itself (most likely anyway) and the new server
should also be using the new DC (I'm assuming DNS is running on the new
domain controller. The important thing is that they use the same name
servers (DNS and WINS) until successful promotion.
