AD/DNS not working after following steps in article 875495

$

0
Two Windows Server 2008 R2 domain controllers. One was cloned, and the clone was introduced into the network. This created AD problems - group policy did not run, users could not access network drives, DNS lookup failures. I followed the steps in article 875495 to fix. All steps were completed: cloned DC forced demoted, metadata cleaned, FSMO roles seized.

DC1 = cloned and demoted server - now a member server
DC2 = domain controller that seized FSMO roles from DC1

Any assistance would be appreciated. Thanks.

****Cannot access DNS Manager on DC2: when DNS Manager is expanded in Server Manager, an error pops up:"The server DC2 could not be contacted. The error was: access is denied. Would you like to add anyway?" If I add the server, the there is a red circle with a white dash through it. There are no zones shown. I tried to add DNS Manager through an empty MMC too, not luck with name, FQDN, IP address or localhost.

All commands and errors are from DC2.

***FSMO
netdom query fsmo
Schema master               DC2..local
Domain naming master        DC2..local
PDC                         DC2..local
RID pool manager            DC2..local
Infrastructure master       DC2..local
The command completed successfully.

****Errors in Event Viewer ->
--DFS Replication:
The DFS Replication service failed to contact domain controller  to access configuration information. Replication is stopped. The service will try again during the next configuration polling cycle, which will occur in 60 minutes. 

This event can be caused by TCP/IP connectivity, firewall, Active Directory Domain Services, or DNS issues. 
 
Additional Information: 
Error: 160 (One or more arguments are not correct.)

--Directory Service:
Active Directory Domain Services was unable to establish a connection with the global catalog. 
 
Additional Data 
Error value:
8430 The directory service encountered an internal failure. 
Internal ID:
3200db0 
 
User Action: 
Make sure a global catalog is available in the forest, and is reachable from this domain controller. You may use the nltest utility to diagnose this problem.

Active Directory Domain Services attempted to communicate with the following global catalog and the attempts were unsuccessful. 
 
Global catalog:
\\DC2..local 
 
The operation in progress might be unable to continue. Active Directory Domain Services will use the domain controller locator to try to find an available global catalog server. 
 
Additional Data 
Error value:
5 Access is denied.

--DNS Server:
The DNS server was unable to open Active Directory.  This DNS server is configured to obtain and use information from the directory for this zone and is unable to load the zone without it.  Check that the Active Directory is functioning properly and reload the zone. The event data is the error code.

--FRS:
Following is the summary of warnings and errors encountered by File Replication Service while polling the Domain Controller DC2..local for FRS replica set configuration information. 
 
 Could not bind to a Domain Controller. Will try again at next polling cycle.

 
--System:
The processing of Group Policy failed. Windows could not resolve the computer name. This could be caused by one of more of the following: 
a) Name Resolution failure on the current domain controller. 
b) Active Directory Replication Latency (an account created on another domain controller has not replicated to the current domain controller).

The processing of Group Policy failed. Windows attempted to read the file \\.local\sysvol\.local\Policies\{31B2F340-016D-11D2-945F-00C04FB984F9}\gpt.ini from a domain controller and was not successful. Group Policy settings may not be applied until this event is resolved. This issue may be transient and could be caused by one or more of the following: 
a) Name Resolution/Network Connectivity to the current domain controller. 
b) File Replication Service Latency (a file created on another domain controller has not replicated to the current domain controller). 
c) The Distributed File System (DFS) client has been disabled.
