I am trying to promote a new server that we just received as a domain controller to an existing domain. The new server(HPDSERVER1) is running Windows Server 2012R2 while the old DC(HPDSERVER) is running Windows Server 2003R2. The new server,HPDSERVER1, is configured with a static ip and dns setting is configured as the ip of the old DC(HPDSERVER). From reading the articles on Microsoft's website, it sounds like we no longer need to run adprep.exe on the old server any longer. It seems as though when you are going through the Active Directory Domain Services Configuration Wizard it should now take care of all of this automatically. The problem arises when I try to add this new server as a domain controller to the existing domain. I specify the domain information(HPD.local) or (HPD), and when I click Next I consistently get an error message stating "An Active Directory domain controller for the domain "HPD.local" could not be contacted. Ensuree that you supplied the correct DNS domain name. I have no problems pinging the old DC with either the hostname or ip address. I have done a nslookup on the new server for hpd.local and HPDSERVER and they both return with a proper ip address of the old server, which is currently hosting DNS. I can also join the new server to the domain. What am I missing?
