Installation Problems with Active Directory on a hosted dedicated server running Windows 2008 R2 Standard.

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.

Try to ping your Domain name (eg domain.local or domain.com) and check
also try restaring the server

I stated above that it wouldn't resolve a ping at first until after I had to manually add an A-Record to the DNS server to point to itself.  It now resolves a ping to "domain.com" which is itself.  

I also restarted the server multiple times.  It was the first thing I did which I failed to mention.

Demote the server and repromote it, as this is the 1st DC for ur domain this would be the easy thing to do

Problems using Powershell and Active Directory?

Managing Active Directory does not always have to be complicated.  If you are spending more time trying instead of doing, then it's time to look at something else. For nearly 20 years, AD admins around the world have used one tool for day-to-day AD management: Hyena. Discover why

One more item to note is we called 1and1.com to resolve this issue but they wouldn't give any technical advice for this issue as they don't openly support Active Directory.  However they did mention that this can be done as others have already.  They also mentioned there were a couple hurdles they had to cross.  One of them being the Local Security Policy.

I did go into the Local Security Policy and open up the ports related to Active Directory.  Still didn't work.  I also tried briefly in opening up every port to see if it may be the issue but this also did nothing.

Also did you build the server or did 1and1?  If 1and1 ask them was it a vanilla build? If not u need tell them you want a vanilla build with no modifications, but patched.

I called up 1and1.com and they finally pointed me in a right direction. I disabled the IPSec service which uses the Packet Filter Policy in Local Security Policies.  Active Directory Users & Computers started right up. They have various blocked ports in their filter list.   Now I'm looking for which ports are specifically needing to be opened as I must have missed one before.
