Windows Server 2012 R2 Problem


  • I have this 4 error on event viewer at my server pc. Also failed when i tried to use command gpupdate. How to fix this. Please help me. Thanks

    1 - 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).

    2 - 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.

    3 - This computer is now hosting the specified directory instance, but Active Directory Web Services could not service it. Active Directory Web Services will retry this operation periodically.

     Directory instance: NTDS
     Directory instance LDAP port: 389
     Directory instance SSL port: 636

    4 - The Kerberos client received a KRB_AP_ERR_MODIFIED error from the server srv-namlifa$. The target name used was LDAP/SRV-NAMLIFA. This indicates that the target server failed to decrypt the ticket provided by the client. This can occur when the target server principal name (SPN) is registered on an account other than the account the target service is using. Ensure that the target SPN is only registered on the account used by the server. This error can also happen if the target service account password is different than what is configured on the Kerberos Key Distribution Center for that target service. Ensure that the service on the server and the KDC are both configured to use the same password. If the server name is not fully qualified, and the target domain (NAMLIFA.LOCAL) is different from the client domain (NAMLIFA.LOCAL), check if there are identically named server accounts in these two domains, or use the fully-qualified name to identify the server.

  • Hi,

    Did you configure DNS configuration correctly?

    The preferred DNS should point to the IP address of domain controller.

    And you could see all domain members’ A records on DNS.

    In addition, if you has enabled firewall, you could try to disable firewall temporarily.

    Best Regards,
