This is the error I'm getting when trying to open Active Directory and Computers on the Domain Controller:

Naming information cannot be located because: The network path was not found.

The NETLOGON service is running.

When I execute the command 'dcdiag', this is what I get:

Directory Server Diagnosis

Performing initial setup:

       Trying to find home server...

   Home Server = DC2012R2

   [DC2012R2] LDAP connection failed with error 0,

   The operation completed successfully..
   [DC2012R2] Unrecoverable LDAP Error 89:

I'm using Windows Server 2012 and am able to use Active Directory Administrative Center.

Any help would be much appreciated!

    1. run netstat –a command to check if port 389 is listening; 2 restart DNS service and check again. 3 Test DNS server with nslookup – stambata Jul 8 '16 at 10:27
