I have a situation where I want to install Microsoft Exchange on a Dedicated Server we leased from 1and1.com. In order to do this I need to install Active Directory on this server.
It currently is running Windows 2008 R2 Standard and is up to date on updates. I set up the role for Active Directory Domain Services and then ran dcpromo.exe to promote the server.
All settings were default, and it set up a local DNS server through the installation. I have done this many times on a local server and everything looks normal.
However once promotion is complete and dcpromo.exe was finished, I launch Active Directory Users & Computers and receive an error. "Naming information cannot be located for the following reason: The server is not operational."
I checked all the services to make sure they were running and they are up as normal. I am getting a couple of event errors: Event ID 1126 for the Active Directory: "...unable to establish a connection with the global catalog." ; and Event IDs 408, 404, and 407 for the DNS server which relate to the bindings and socket openings.
After the initial installation, I could ping outside but couldn't ping the internal domain name set up during dcpromo.exe. So I set up an A-Record to point to itself for its own domain name resolution so it resolves a ping, but I still get the same error up when launching AD Users & Computers.
Any help would be much appreciated.
