DCDIAG " VerifyEnterpriseReferences" Failed

From last few days we are observing that our ROOT DC is giving very slow response when anybody is trying to log in. Post running all the command, we have got the below error. It's basically DCDIAG command for testing all the key services in the Domain Controller.
     Starting test: VerifyEnterpriseReferences
         The following problems were found while verifying various important DN
         references.  Note, that  these problems can be reported because of
         latency in replication.  So follow up to resolve the following
         problems, only if the same problem is reported on all DCs for a given
         domain or if  the problem persists after replication has had
         reasonable time to replicate changes.
            [1] Problem: Missing Expected Value
             Base Object: CN=LostAndFoundConfig,CN=Configuration,DC=CONTOSO,DC=COM
             Base Object Description: "Server Object"
             Value Object Attribute: serverReference
             Value Object Description: "DC Account Object"
             Recommended Action: This could hamper authentication (and thus
            replication,  etc).  Check if this server is deleted, and if so
            clean up this DCs Account  Object.  If the problem persists and
            this is not a deleted DC, authoratively restore the DSA object from
            a good copy, for example the DSA on the DSA's home server.
         ......................... FORESTROOTDC failed test

Connect to the "Configuration" partition using ADSIEdit and browse to "CN=LostAndFoundConfig,CN=Configuration,DC=CONTOSO,DC=COM" verify that the ntdsa object belongs to a demoted/deleted DC - if so delete the object(s)
Open the ADSI Edit MMC snap-in.
On the Action menu, click Connect to.
In the Connection Settings dialog box, in the Name field, enter a name for the ADSI connection. Under
Connection Point, select Select a well known Naming Context, and then select
Configuration in the drop-down menu. Click OK.
In the left pane, double-click the Configuration object, and then double-click
LostAndFoundConfig.
In the right pane, delete all objects and containers. Right-click the object or container, click
Delete, and then click Yes.
Exit ADSI Edit.

  • Error with ADC on Azure dcdiag report failed test Advertising

    ever since I built an ADC on azure for my domain I am getting the below errors on dcdiag

  • DCDiag: SERVER6 failed test Advertising

    This is one of quite a few errors I get after running a dcdiag on this particular domain controller:
       Testing server: Default-First-Site-Name\SERVER6
          Starting test: Advertising
             Warning: DsGetDcName returned information for
    \\server5.domain.local,
             when we were trying to reach SERVER6.
             SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE.
    Anyone know what might be going on here? Why is information being returned for server5 instead of server6?

    Hi,   
    The error message SERVER IS NOT RESPONDING or IS NOT CONSIDERED SUITABLE could be caused by that sysvol and netlogon share are not available.
    Here are some suggestions for you:
    Please open CMD then run "net share" command to confirm if they are shared successfully.
    Make sure that needed ports for AD replication are not blocked in both directions and each DC has one IP address and one NIC card.
    Make sure both DCs point to your DNS servers correctly. In addition, you can run ipconfig /registerdns and restart netlogon on each DC to re-register DNS records.
    More detailed information, please refer to following threads:

    I have found the solution.
    The server (AUCHMAIL1) was removed awhile back, but the reference to the server still remained in ADSI. I deleted the old server entry via ADSIedit.msc (Domain -> DC -> CN=System -> CN=File Replication Service -> CN=Domain System Volume (SYSVOL
    share) -> CN=AUCHMAIL1) and confirmed no further errors thrown against 'VerifyEnterpriseReferences' during a DCDIAG.

  • AD Upgrade

    Dears,
    I have deployed my new DCs in all of my sites, then I have done with below:
    Moved FSMO roles to new DCs
    Configured bridgehead servers
    Remove check box of GC from my old DCs
    Make sure that my new DCs are GCs
    I configure all my DCs, Servers, and Clients TCP/IP DNS settings to use my new DCs
    My DCs does not include encrypted data
    Now I need to test my environment for 10 days, while my old DCs are shutdown.
    I shutdown my old DCs, I run the command: "dcdiag /test:dns" and it fail.
    So how should I test my environment while my old DCs are shutdown?

    >>>So how should I test my environment while my old DCs are shutdown?
    DCDiag will fail (you will see error message) if you haven't completed the metadata cleanup. So you can ignore these errors. Why do you need to keep these DCs down? 
    Anyway, here are some high level steps:

  • Dcdiag dns checks failing on external update attempt

    It does sound like you're using an external DNS on that server instead of the internal ones.

    While preparing to demote a DC I ran dcdiag and it's failing while attempting to register records in our external dns server at rackspace. I can only assume that since we use the same domain externally, and for AD, that the domain controller is seeing rackspace as authoritative and attempting to create the test records there. Has anyone seen this behavior before? It's never been a problem until now, and this issue did not appear in the logs when I demoted another DC earlier tonight.
    Log:TextAn error event occurred. EventID: 0x0000168E Time Generated: 11/15/2010 15:37:52 Event String: The dynamic registration of the DNS record 'ForestDnsZones.contoso.com. 600 IN A 192.168.1.234' failed on the following DNS server: The DNS server it goes on to list is the public IP of our rackspace DNS.There are many of these errors listed as it attempts...

  • Dcdiag failing dns tests

    w2k8 domain with two DCs - this error is present.
    initially we had issues with initial synchronization of the directory by we logged a call with MS and they address a registry entry that bypassed the initial syncronization, but I can still see the errors below and a client not registering in DNS sue to no permissions.
    canyou advise what can I do to get rid of this error:
    Log Name:      Directory Service
    Source:        Microsoft-Windows-ActiveDirectory_DomainService
    Date:          28/10/2009 18:54:04
    Event ID:      2088
    Task Category: DS RPC Client
    Level:         Warning
    Keywords:      Classic
    User:          ANONYMOUS LOGON
    Computer:      olivia.domain.com
    Description:
    Active Directory Domain Services could not use DNS to resolve the IP address of the source domain controller listed below. To maintain the consistency of Security groups, group policy, users and computers and their passwords, Active Directory Domain Services successfully replicated using the NetBIOS or fully qualified computer name of the source domain controller.
    Invalid DNS configuration may be affecting other essential operations on member computers, domain controllers or application servers in this Active Directory Domain Services forest, including logon authentication or access to network resources.
    You should immediately resolve this DNS configuration error so that this domain controller can resolve the IP address of the source domain controller using DNS.
    Alternate server name:
     katie
    Failing DNS host name:
     60c35a20-978b-4e86-9751-e65d9e584e76._msdcs.domain.com
    NOTE: By default, only up to 10 DNS failures are shown for any given 12 hour period, even if more than 10 failures occur.  To log all individual failure events, set the following diagnostics registry value to 1:
    Registry Path:
    HKLM\System\CurrentControlSet\Services\NTDS\Diagnostics\22 DS RPC Client
    User Action:
     1) If the source domain controller is no longer functioning or its operating system has been reinstalled with a different computer name or NTDSDSA object GUID, remove the source domain controller's metadata with ntdsutil.exe, using the steps outlined in MSKB article 216498.
     2) Confirm that the source domain controller is running Active Directory Domain Services and is accessible on the network by typing "net view \\<source DC name>" or "ping <source DC name>".
     3) Verify that the source domain controller is using a valid DNS server for DNS services, and that the source domain controller's host record and CNAME record are correctly registered, using the DNS Enhanced version of DCDIAG.EXE available on http://www.microsoft.com/dns
      dcdiag /test:dns
     4) Verify that this destination domain controller is using a valid DNS server for DNS services, by running the DNS Enhanced version of DCDIAG.EXE command on the console of the destination domain controller, as follows:
      dcdiag /test:dns

  • DCDIAG Result A net user or LsaPolicy failed with error 67

    I have looked through all the similar posts and have ran an Authoritative and UnAthroativte process. This allowed my SYSVOL to replicate and come back. I still keep getting this error on the one DC. Everything else passes fine. I am pulling my hair out
    if anyone has had this problem please help. Also this is a Server 2012 R2 DC 

    Hi Mike,
    Before going further, how did you do the Sysvol restore? What’s our Sysvol replication mechanism, FRS or DFSR?
    If our Sysvol replication mechanism is FRS, we need to do an authoritative (D4) restore on a healthy DC and non-authoritative (D2) restore on other DCs.
    Regarding this point, the following thread and article can be referred to for more information.

    If our Sysvol replication mechanism is DFSR, we can follow the article below to do the Sysvol restore.

  • The processing of Group Policy failed. Windows attempted to read the file...

    Hello all-
    I am currently trying to configure group policy (specifically folder redirects) from a new Windows Server 2008 in my home... the server acts as both an AD DS and file server for 4 client computers, all running Windows Vista Ultimate.
    Here are the steps I am currently taking:
    I create a new Group Policy called All Users and Computers and apply it to the All Users and Computers OU, which contains exactly what it says (all users and computers in the domain).
    I verify that a new folder was created in \\<FQDN>\sysvol\<FQDN>\Policies.  The new folder created is named {6479C8E0-3134-4B4F-B047-7ADD51684684}
    I change the GPO Enforced setting to Enforced.
    I attempt to use the gpupdate command to see if the group policy can be updated successfully.  In a command prompt, I type gpupdate <enter>.  I receive the message 'Updating Policy...' then after about 15 seconds the message 'User Policy update has completed successfully.'
    I keep the cmd window open.  After about 10 seconds another message apperas which says "Computer policy could not be updated successfully.  The following errors were encountered: The processing of Group Policy failed.  Windows attempted to read the file \\<FQDN>\sysvol\<FQDN>\Policies\{6AC1786C-016F-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.
    To diagnose the failure, review the event log or invoke gpmc.msc to access information about Group Policy results."
    I confirm that the error code is #3 using the Event Log, "The system cannot find the file specificed"
    Of course the system cannot find the file specified because the folder does not exist in the sysvol folder. I am wondering why Windows is trying to read from this location when it does not exist, and is not the new group policy I created!  I have no other group policies linked or enforced to any other OU/Domain/etc.  Any help resolving this issue would be greatly appreciated.

    Hello all and thanks for the help.  First a few things:
    I understand that the DC should not be running RRAS, but this a simple server being used in aa home environment by 4 users and getting another server just for RRAS would be overkill.
    Secondly, I currently have it so that while the router is handling DHCP, I have reserved a fixed IP for the server, so it always has 192.168.1.100.  If I were to use the server as the DHCP, what would my hardware configuration have to look like?  I currently have the router plugged into the ISP modem, and then server plugged into the router.  All other clients connect to the router wirelessly.
    Here's the dcdiag output.  I tried dcdiag /fix but to no avail.

  • Deleted failed DC from the domain (Server 2012 R2) - Now after doing metadata and DNS cleanup, I can no longer promote a new DC to the domain

    I work for a university and teach IT courses to undergrad and graduate students. The details below are pertaining an isolated lab environment
    I had a storage failure in my lab and the DCs became corrupt. This is a university lab environment so there isn't anything crucial on here. I just would rather avoid rebuilding the domain/forest and would rather use this as a learning experience with my
    students...
    So after the storage failed and was restored, the VMs hosted became corrupt. I did a NTDSUTIL to basically repair the NDTS.dit file but one of my DCs reverted to a state before DC promotion. Naturally, the domain still had this object in AD. After numerous
    failed attempts at trying to reinstall the DC on the server through the server manager wizard in 2012 R2, I decided that a metadata cleanup of the old failed object was necessary.
    Utilizing this article, I removed all references of the failed DC from both AD and DNS (http://www.petri.com/delete_failed_dcs_from_ad.htm) 
    So now that the failed object is removed completely from the domain and the metadata cleanup was successful, I then proceeded to re-install the necessary AD DS role on the server and re-promote to the existing domain. Pre-Requisites pass but generate some
    warning around DNS Delgation, and Dynamic Updates (delegation is ignored because the lab is isolated from external comms, and dynamic updates are in fact enabled on both my _msdcs and root domain zones).
    Upon the promotion process, I get the following error message (also worth mentioning - the account performing these operations is a member of DA, EA, and Schema Admins)
    The operation failed because:
    Active Directory Domain Services could not create the NTDS Settings object for this Active Directory Domain Controller CN=NTDS Settings,CN=domainVMDC1,CN=Servers,CN=Default-
    First-Site-Name,CN=Sites,CN=Configuration,DC=domain,DC=school,DC=edu on the remote AD DC domainVMDC2. Ensure the provided network credentials have sufficient permissions.
    "While processing a change to the DNS Host Name for an object, the Service Principal Name values could not be kept in sync."
    As you can see, this error seems odd considering. Now that I'm down to a single DC and DNS server, the sync should be corrected. I've run a repadmin /syncall and it completed successfully. Since then, I've run dcdiags and dumped those to a text as well and
    here are my results...

    From what I can gather, there is a definite DNS issue but I don't have any stale records to the old DC stored anywhere. I've tried this with a new server as well and get similar errors... 
    At this rate I'm ready to rebuild the entire forest over again. I'm just reluctant to do so as I want to make this a learning experience for the students. 
    Any help would be greatly appreciated. Thanks!

    As you can see, there seems to be some errors. The one that I did correct was the one around the _msdcs NS record being unable to resolve. For whatever, reason the name wasn't resolving the IP but all other NS tabs and records were. Just that one _msdcs
    sub-zone. Furthermore, the mentioning of any connections to root hint servers can be viewed as false positives. There is no external comms to this lab so no communication with outside IPs can be expected. Lastly, they mentioned a connectivity issue yet mention
    that I should check the firewall settings. All three profiles are disabled in Windows Firewall (as they have been the entire time). Thank you in advance for your help!

  • Secondary DNS failing to redirect clients when Primary DNS goes down

    I have a single domain with two Windows 2008 servers, DC1 (physical) and DC2 (virtual).  Both servers run DNS and are GC servers, and the entire domain is on the same subnet (192.168.0.x). 
    All clients on the network are configured to use DC1 as primary DNS, DC2 as secondary DNS. 
    DHCP is enabled only on DC1.  (This might be part of the issue, not sure).
    The problem is that when DC1 goes down for a reboot or repair, we lose access to the internet from our clients.  Trying to pull up any website results in a "Page cannot be displayed" error.  DC2 is available during this time and can be
    pinged from any client but does not resolve DNS requests, even if I specify it as the primary DNS server on one of my workstations.  However I can log on to DC2 locally and browse the web. 
    Here are the results of a DCdiag /dnsall from DC2 (I bolded areas of concern):

    Looks like it may be trying to forward to a machine that's down (DC1 and another 192.168.0.7) and root hints aren't available.
    Check out this article:
    http://technet.microsoft.com/en-us/library/ff807391(v=ws.10).aspx
    See if you can enable DNS access through the firewall to the Internet if it's not already available.  Try to match whatever forwarder settings are on DC1, or remove them entirely and let the server resolve DNS from Internet root servers.  Alternativly,
    you could change your forwarder to a public DNS server you have access to, your ISP should supply this or you could test with something common like 4.2.2.2.

             ......................... LEGACYDC failed test

    The note above is correct, the IPs in your DCDIAG are all public DNS servers:
    208.67.220.220 and 208.67.222.222 are OpenDNS
    8.8.8.8 and 8.8.4.4 are Google's DNS servers
    The KB article that is referenced is calling out deleted FRS objects, so you may have some corruption in your AD environment. 
    I would take a look at the DNS, FRS, and other AD related logs and see what is there.  Hopefully you have a recent backup that you can recover with if needed.
    Although it is possible the issue is that your account does not have the rights to run the dcdiag.  The event logs should have additional details that help.

    Hi Tony,
    Srry but No.  We just installed the monthly updates.
    I went back and found I had missed removing a patch.  I missed the rollup for Windows Server 2003:
    Event Type: Information

    Description:
    Windows Server 2003 KB954920 was removed from your computer, and the previous Windows Server 2003 configuration was restored.
    After I removed that is still didn't work but after about five minutes it started working.
    I guess I ned to report that to MS after I research what might be changed to make the patch work.
    Every time I get stuck and ask for help it seems to be just before I stumble on the solution.
    Thanks for replying.
    Well - maybe this will help someone else.
    Thanks again for replying Tony

  • I_NetLogonControl failed: Status = 5 0x5 ERROR_ACCESS_DENIED

    I have a single DC on a single domain that is both a PDC and DNS server. Windows Server 2012.  This is the only DC. I cannot join new PC's to domain. I am getting DNS could not resolve to domain controller. The new pc's can resolve by name to DC. Also
    the existing PC's are take 5 minutes or more to get to the desk after cred's are put in. This just started happening. 
    I am getting netlogon errors. 5774. Any Idea's ?
