A trace of the network traffic during the dcpromo process revealed a connection attempt from the local computer to one of the DCs in the root domain using the computername and username of the local computer. This of course fails since the local computer is to become the first domain controller in the new child domain and thus is in a workgroup.
Disconnect all previous connections to the server or shared resource and try again. I restarted dcpromo and ran it all the way up to the summary screen.

Windows could not authenticate to the Active Directory service on a domain controller. LDAP Bind function call failed. Look in the Details tab for error code and description. Can anyone give me any troubleshooting clues on how to figure out why I can't successfully promote these servers to DCs? I've used almost this identical setup in a dozen different branches around the world with no problems, so I'm thinking this must be something unique to the local connection You may have better luck promoting to DC from media, as described in this MS TechNet article Basically, you will move all necessary data in one go with a packed file, instead of establishing all those connections over your high latency connections.
After promotion there will be need of regular replication, which will be retried continuously and, hopefully, some will succeed. Sign up to join this community.

Logging in took about 10 minutes on one machine and 20 minutes on the other machine. Average ping is around ms.

It may be your incredibly slow connection, other than that make sure you have full access to the other domain controllers and no firewalls are blocking required ports.
From experience, the "The wizard cannot gain access to the list of domains in the forest. The fact that you joined domain successfully over this link eliminates the possibility of bad network configuration, that would have spoiled RPC connection.
The fact that the latency is that high and resulting bandwidth is very low introduces a very high chance of failure in promotion, as any connection would be subject to timeout, resulting in a failure after a long wait. Yes, in fact i just left the domain and then rejoined it for test purposes. No problems other than very slow. It's been stuck on that step for more than an hour, on both machines.

Active Oldest Votes.Hello, Just added a new server to our domain. DNS is set up correctly it can ping my other 2 servers both r2s. Put AD role on and go to configure and get hit with :. I am on the domain admin account.
I should not be denied anything. So both old servers are having DC issues for a while which is why we got the new server to be our primary DC. Not too much out there about it besides make sure there is an A record which there is or disable a WAN optimizer which we do not have on this server.

Thank you I will do that. Looks like the time is wrong on the DCs time skew will break Kerberos. Make sure you fix the clocks. Based on your own comment you are having replication issues, so you will only make them worse by adding yet another DC to the mix, don't do that, fix your issues first otherwise you simply move the problem.
Also I don't think I have sysvol or netlogon folders on DC01 and on DC02 there is nothing in the netlogon folder and in the sysvol folder there is a shortcut folder with my domain name and in it is ClientAgent, Policies, scripts, StarterGPOs also the same files but their names are in blue.
