DNS Forwarders say unable to resolve. Root Hints timeout during validation.

I have a Windows Server 2012 Essentials server that has been up and running for a year. The Server is the domain controller with the DNS server role installed. There is only one NIC card used on the network. Today, DNS stopped working. The server and the
clients can access internet websites if IP addresses are used; otherwise, accessing websites fails. Looking at the DNS properties page on the Forwarders tab, I see that each DNS server listed (which are the DNS servers given to me by my ISP
provider) says <Unable to resolve>. When I saw that those addresses were not resolving, I added Open DNS IP addresses and I added google's DNS addresses in the DNS forwarders list but they too said <Unable to resolve>.
I can ping the Open DNS IP addresses, the google DNS IP addresses and the ISP provider's DNS IP addresses. NOTES: 1) I tried unchecking IPv6 on the DNS' server's Ethernet adapter properties; 2) I have done a flushdns; 3) I have verified that
my DNS services are running; 4) the first DNS on my server's Ethernet adapter properties is the IP address of the DNS server (which is 10.0.0.51) and the second is the loopback (127.0.0.1); 5) the power management on the NIC adapter is disabled; 6) nslookup
works for 8.8.8.8 but not for www.google.com.
I removed the Forwarders and tried to use just Root Hints. That didn't make any difference. I went back into DNS Manager->[DNS server name]->right-click properties->select Root Hints tab. I clicked on a.root-servers.net to edit. Under the Validated
column it says "a timeout occurred during validation". I clicked cancel to back out of everything I was doing.
As I mentioned, this was all working fine until this morning. Can someone tell my why the Forwarders are unable to resolve? An why the Root Hints timeout during validation?

Hi,
It could be a firewall issue. Try to use public DNS server to resolve names,
nslookup
server
IP address of the public DNS server
www.microsoft.com
If timeout occurs, it means that firewall or some other similar device block the DNS traffic. Please disable the firewall and try again.
If issue persists, please try to restart the DNS service.
If it still doesn’t work after restarting the DNS services, please check if there is any warning or error in the event viewer of DNS servers.
Best regards.

  • Win 2012 R2 DNS Root hints

    Hello,
     As part of the Win 2003 to Win 2012 AD upgrade we installed our new WIn 2012 DC. When i run the BPA for DNS, I find few of the root hint server are not resolved.
    I get the following error
    DNS: Root hint server 192.33.4.12 must respond to NS queries for the root zone.
    The root hint server 192.33.4.12 is not responding.

    I wonder has anyone noticed these errors and resolution.

    If you bring up a cmd prompt and then run :
    nslookup
    followed by :
    server 192.33.4.12
    (picking a server at random), does it connect and resolve to c.root-servers.net or does it time out (if it times out, try exiting nslookup and repeating it a second time, as I've had issues the first time myself)? If it's never able to connect then I'd wonder
    if something is blocking you from making outbound DNS queries from your new server. Certainly those IP's match my list of root servers, and they work from my lab DNS install.

  • Unable to resolve single DNS name using root hints

    Recently, we had reports that we could not internally resolve a certain .com domain name (discovered by undeliverable e-mails).  A lookup using an external server (Google's in our case) resolves the .com name just fine.
    Long ago, we had another DNS issue that lead us into implementing the following registry change:
    https://support.microsoft.com/kb/968372?wa=wsignin1.0
    1. Start Registry Editor (Regedit.exe).
    2. Locate the following registry key:
    HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\DNS\Parameters
    3. On the Edit menu, click
    New, click DWORD (32-bit) Value , and then add the following value:
    Value: MaxCacheTtl
    Data Type: DWORD
    Data value: 0x2A300  (172800 in decimal = 2 days)
    That is the only DNS change that we have made.  We are using root hints, but temporarily added Google DNS as a forwarder so that we are able to resolve this .com address.
    As a test, I did remove that registry entry, restarted the DNS service and tested again to no avail.
    Any starting points?

    Hi,
    According to your description, my understanding is that DNS server can’t resolve .com with its root hint.
    Could you provide more information about the DNS architecture, such as numbers of DNS servers, their locations and relationships, system version, etc.
    And please post the results of NSlookup test(use local DNS server, and then use Google's server to resolve name ) here.

  • In what order are root hint DNS servers used?

    Hey guys, I was wondering how the list of root hints were actually used when the DNS server performs iterative queries. 
    Since it's a list that seems to be in alphabetical order, does it simple use a.root-servers.net. first until it is unavailable, and go down the list? That seems unlikely since that one root would receive disproportional load compared to the others. I am
    aware that most of the roots use anycasting, so multiple servers are behind each entry. 
    Maybe it's round-robin? 
    I suppose I can capture packets and see what is actually going on... I might do that if no one replies!

    Hi Anton2,
    Thank you for posting here.
    I searched many articles about root hints, but it seems that there is not similar articles which mentioned the used order of root servers.
    As you said above, I captured packets in my lab. The DNS server didn’t use the alphabetical order to query these root servers. And I didn’t find the round robin phenomenon.
    Capturing packets is a good method to verify your ideas. Just do it.
    For more details about cache.dns file, please refer to the article below,

  • Unable to resolve server's DNS address.

    Been sharing my internet (ethnernet) with another Mac OS X 10.6 via airport, but the other mac is unable to resolve server's DNS address. Help?

    Hi,
    Have you contacted your internet service provider (ISP) as DNS usually are ISP related. Have they reset their modem or router,  not just power cycle?
    I suggest you change the Preferred DNS server, try the following steps:
    1. Click "Start", input "NCPA.CPL" (without quotation marks) and press Enter.
    2. Right click on the connection that you use for the local connection, and then click "Properties".
    3. Click to select "Internet Protocol Version 4 (TCP/IPv4)", and then click "Properties".
    4. In the Internet Protocol window, let's change the "Preferred DNS server" to 208.67.222.222
    5. Click 'OK' twice to complete the modification.
    If the issue persists, please repeat the steps and change the "Preferred DNS server" to 208.67.220.220.
    Also, if the issue persists, I suggest you run the following command:
    ipconfig /release
    ipconfig /renew
    To get IP address & DNS from DHCP, the DNS server should be internal DNS server IP.
    Hope this helps,

  • DNS Root Hints

    hello guys, i had a windows 2012 and windows 2008 as DC's of course with DNS installed on both of them.
    The two DC's uses root hints for DNS. (NO forwarder)
    No changes made for over a year.
    We have a hardware firewall, configured as DHCP.
    The DNS IP on the DHCP, is pointing to  the Windows box.
    Out of the blue, the DNS just stop working and some websites doesn't display.
    If I ping public DNS such as 8.8.8.8  it works fine i get good replies and the Win 7 clients and the Server box also indicates that the internet is up.
    The internet is up, but the web pages does not display.
    I restarted the DNS Service, but doesn't help and still some websites are not displayed.
    What I did to remedy the problem is to put a public DNS on the DHCP. (of course this is not a good practice)
    So the DNS settings got the 2 DC's IP and 1 public DNS.
    I'm actually suspecting that the Hardware Firewall is going south since it's more than 8 years(I think could be more).
    I had checked the DNS event logs, i found no issues.
    Any ideas guys? What could be the real culprit on this case?
    Please help.. Thanks.

    Hi cguan,
    Please run "ipconfig /flushdns" on both of DNS server and client. Then run "dnscmd /clearcache" on the DNS server.
    If it doesn't work, please try to run nslookup in debug mode,
    nslookup
    set d2
    domain name of the website
    If it is possible, please post the result here.
    If timeout occurs, please enable the DNS debug log. It may give some hints.
    Best Regards.

    Hi Steven,
    Appreciate the reply.
    Prior to adding the Public IP in DHCP, i actually did the "ipconfig /flushdns" and also clearing the DNS cache using the GUI.
    But after doing it, some website still doesn't open.
    I'm not sure whether it's the hardware firewall is going south.
    Why I said this, we have a wireless outside the firewall. When the private LAN was having issue, the wireless outside the firewall was working fine.
    The network right now, is okay. But the only thing; there is a public IP on the DHCP on every client. Which should not be there as part of best practice.
    I will try the debug mode, and update this post.
    Thanks. :)

  • HomeHub is unable to resolve a DNS CNAME pointing ...

    Just sent a technical compaint email off to BT to get an answer to this, but thought I would share here in case it helps anyone else.
    Problem:
    My HomeHub 3 is unable to resolve DNS queries where the DNS has a CNAME pointing to my WAN address. BT's and other public DNS servers resolve correctly - so the problem is not with the DNS record.
    Background:
    I have some devices at home which use DNS for name resolution. As a web developer, it is anoying that I have to use a different DNS name from inside my house to outside because of the above problem. It is also annoying that the only two workarounds I can think of are to a) buy a new (non-BT) router, or b) manually configure each device to not use the HomeHub for name resolution because BT have locked down the hub so I can't do it automatically.
    Reproduce steps:
    1) Set up a DNS record to point to your HH WAN address.
    2) Set up a second DNS record that ponts to the first with a CNAME.
    3) DNS queries to the first record succeed, queries to the second fail.
    4) Set up a DNS record to a different IP address (try adding 1 to your WAN address)
    5) Set up another CNAME to point to that address
    6) DNS queries to both addresses succeed because the CNAME doesn't point to your WAN address
    There are some other people experiencing this:

    For completeness - the reply from customer services:
    First of all, thank you for your email. I can certainly understand that a problem like this can cause frustration and inconvenience and I’m very sorry.
    At the BT Broadband Technical Helpdesk we can only help with an actual broadband fault. The scope of free technical support for your broadband is limited to the supply of a broadband connection to one computer with the Homehub at it's default settings.
    I understand that you have specific setup requirements. I'm sorry that I'll be unable to help configure the Homehub the way you'd like it to work.
    I'd recommend that you contact our Home IT Experts Service where one of my colleagues will be able to help you.

  • DNS Server - How does it resolve queries that aren't in it's zones?

    Footy wrote:
    Also if you have multiple DNS servers pointing at each other and no root hint or forwarders you get stuck in a loop of the two machines querying each other over and overNo. It doesn't. If the DNS server has no forwarders or root hints then it doesn't know how to get any further answers to the query so it returns a negative response. Read RFC 2308.

    So I'm trying to learn more about the basics of DNS, specifically DNS servers as that's what I'm having trouble with in my environment and trying to learn more about to fix.I know what DNS is and I think I have a pretty good handle on how it does what it does, but where I'm having trouble keeping up is figuring out how it resolves things outside of my local domain.For example, everything I've seen in searches says that if you've got two DCs on your domain you should have it set up like this:On DC1:DNS1: DC2DNS2: DC1On DC2:DNS1: DC1DNS2: DC2And you should have the workstations in your environment set with DC1 and DC2 as their primary and secondary DNS servers. Is that correct?If it is correct, then what happens when someone in the network goes to say www.google.comconsidering I don't have that name or IP address in my server's lookup...

  • DNS Forwarders with no recursion

    As I understand it, Windows DNS has a problem with its recursion (being attacked recently). But if you turn it off, and turn off internet access (forwarders). Is there a way to turn off recursion, and still allow the DNS server to use the root hint servers? 
    Other DNS servers?
    If, as I suspect, the answer is no.  Is there a way to disable recursion, but still allow certain domains (say domains that I control) to resolve.  As an example;
    DomainA.edu is prod
    DomainB.edu is test
    I don't really care if DomainB can see google, but I do want DomainB too be able to resolve DomainA.  There is no Active Directory or other connection between the domains.
    Can I do an import of DomainA or something to that effect (A manual zone transfer say)

    Do you have a link that you can share with more information on that attack issue you are referring to? - Thanks.
    Or perhaps you are talking about DNS Cache Poisoning?
    There are two separate Recurision settings - one under the Advanced tab, and one under Forwarders.
    Advanced tab: If you disable the one under Advanced, then your DNS server effectively becomes a Root server and won't recurse at all, meaning it will not use root hints (because it thinks it's one of them), and won't Forward (since that's
    a recursion request. This effectively also makes it a content only server where whatever zones it hosts, is all it will resolve for requests.
    Forwarders tab: If you disable it under Forwarders, it won't look further if the forwarder(s) fail(s).
    You could theoretically set a conditional forwarder to a specific DNS, such as 2.2.2.2 for example, for DomainA.edu, and set the checkbox for no Recursion just for that domain, so it will only send the request to 2.2.2.2, then on 2.2.2.2 is set
    to not allow recursion under the Advanced tab.
    You could also setup one or two separate DNS servers in your DMZ that are not part of your domain and that have the MaxCacheTTL set to 0 so it won't cache, and have them just use the Roots and host no zones. Then internally, you can forward to
    them, which they in turn will resolve external data. This is a secure setup that meets PCI DSS requirements (Payment Card Industy Data Security Standards). I myself work at a university hospital with 27k mailboxes. Without getting into specifics, this is part
    of our setup, which meets HIPAA requirements.
    Here's a secure setup (not neccessarily what we have in our establishment):
    Here's a detailed discussion about Forwarders, recursion, etc:

  • OracleConnection.createARRAY: Unable to resolve type

    Hi All,
    for some good reasons (don't ask ...) I need to implement a solution where a directory listing, on the DB server machine, can be gotten via an sql query.
    I have to say I am not very experienced with Java in Oracle, please forgive the newbie mistakes.
    Environment: 11gR2 on Win7, SQLDeveloper as front-end.
    In order to do this, I created a simple Java class, DB types and PL/SQL wrappers as follows:
    CREATE OR REPLACE TYPE T_FS_ENTRY AS OBJECT (
      is_dir CHAR( 1 )
    , entry_name VARCHAR2( 4000 )
    , entry_size NUMBER
    , last_modified NUMBER );
    CREATE OR REPLACE TYPE T_FS_ENTRY_TAB IS TABLE OF T_FS_ENTRY;

    At last I granted privileges on a directory:
    BEGIN dbms_java.grant_permission( 'FPL_XSD', 'SYS:java.io.FilePermission', 'C:\-', 'read,write,execute' ); END;
    COMMIT;
    When I test this as FPL_XSD user, the same schema where the type, package and source are defined:
    select * from table( QAO_SUPPORT.get_dir_list( 'C:\\TEMP' ) );
    I get the following error (sorry for the dutch stuff, basically, "uncaught java exception: error in creation of descriptor:..."):
    ORA-29532: Java-aanroep is afgesloten door niet-onderschepte Java-uitzondering: java.sql.SQLException: Maken van descriptor is mislukt.: Unable to resolve type: "FPL_XSD.T_FS_ENTRY".
    ORA-06512: in "FPL_XSD.QAO_SUPPORT", regel 30
    Even if it is not exactly stated the error happens at the line:
    ARRAY oracleCollection = conn.createARRAY( "T_FS_ENTRY", retArray );
    Note that when logged in as FPL_XSD, desc T_FS_ENTRY returns the type description.
    I searched everywhere and consulted the documentation. I think it should work. I am out of ideas, but I have a suspect the problem might be with the connection configuration, maybe?
    Any help or hint is greatly appreciated.
    Kindly,
    Andrea

    Hi All,
    I insisted trying and I found out what the problem was. In:
    ARRAY oracleCollection = conn.createARRAY( "T_FS_ENTRY", retArray );
    The first argument is an Oracle type name, I wrongly used the RECORD (OBJECT) type name - T_FS_ENTRY -, not the name of the nested table T_FS_ENTRY_TAB.
    So the code should look like:
    ARRAY oracleCollection = conn.createARRAY( "T_FS_ENTRY_TAB", retArray );
    Which works.

  • VersaMail - "Unable to resolve name" error for mail server

    I've had an intermittent but frequent problem with VersaMail when I try to connect to get my email.  I frequently get the following message:
    "Unable to resolve name pop.mindspring.com. Check your DNS settings or enter the IP address for your mail server."
    I also get it occasionally for my Yahoo.com mail addresses as well, so it's not unique to Mindspring.com.  Sometimes it happens a lot, but sometimes I get right in with no problems, so the settings I have appear to work - when they want to.  Needless to say, it's frustrating and annoying, so if anyone has a way to resolve this, I'd appreciate knowing it.
    Thanks.

    This question was solved.
    View Solution.

    Problem solved!  I had Googled for answers and had found an explanation of DNS servers on another forum where someone was having a similar problem.  It seems that DNS servers simply take the domain name we use and search for the IP address for that domain name, then hook us up to that IP address.  The error message I was getting was that I needed to check my DNS settings or enter the IP address, so it seemed only logical to me that if I could bypass those goofy DNS servers with their "now I'll do it, now I won't" bad attitude, perhaps I could connect directly with the mail servers.  Your tip on how to find the IP address of the mail servers by pinging them was the missing piece I needed.  I deleted the POP and SMTP server names for each account I'd set up in VersaMail, replacing them with the appropriate IP addresses, and I can now connect reliably with any of the servers, first time, every time - and lightning fast.
    Thanks for your help!

    No it's not stealing. They have an allowance that you can share with so many computers/devices. You'll have to authorize her computer to play/use anything bought on your acct. You can do this under the Store menu at top when iTunes is open on her computer.
    As far as getting it all on her computer....I think but I am not sure (because I don't use the feature) but I think if you turn on Home Sharing in iTunes it may copy the music to her computer. I don't know maybe it just streams it. If nothing else you can sign into your acct on her computer and download it all to her computer from the cloud. Not sure exactly how to go about that, I haven't had to do that yet. I wonder if once you authorize her computer and then set it up for automatic downloads (under Edit>Preferences>Store) if everything would download. Sorry I'm not much help on that.

  • [Solved] Unable to find root device

    Hi guys,
    it's been three days now that my laptop refuses to boot with a message from systemd like this:
    ERROR: device 'UUID=xxx...' not found. Skipping fsck.
    ERROR: Unable to find root device 'UUID=xxx...'.
    You are being dropped to a recovery shell.
    That said, keep in mind that I'm saying "three days" just because it's in the past two days that I've spent most of the time searching in the Internet for a solution of what seems just to be a well-known, very common problem, especially when it arises after a kernel upgrade (as in my case).
    But believe me, I've been trying this and that through the live Arch Linux environment, but without the slightest improvement: regeneration of the initramfs, regeneration of /etc/fstab, reconfiguration of GRUB (although this was clearly unhelpful, since the problem arises when the kernel has already been booted), small changes in the hooks in /etc/mkinitcpio.conf, small changes to some modules loaded at boot, downgrading linux... Nothing works.
    I'm now writing from another computer, so I cannot post the entire output of useful commands now, but if you need to know something I will give you the necessary information.
    In the meanwhile, notice that I use Linux LVM partition with logical volumes formatted with Btrfs, without encryption.
    It's strange that even with the dowgrade from Linux 3.18.3 (the one after whose installation the system was unusable) to 3.18.2 the problem still remains.
    However, the only thing I managed to take from my system is the output of dmesg, obtained from the recovery shell, after having set the debug settings for systemd in the kernel command line before booting.

    Guys, I think I've found the strange thing.
    First, in the recovery shell, when I type "lvm lvscan", it prints:
    WARNING: lvmetad is running but disabled. Restart lvmetad before enabling it!
    and then it says that all four my logical volumes root,boot,home and var are inactive.
    So I tried to set them up manually, with "lvm vgchange -a y", and guess what happened: I was able to boot!
    I still haven't managed to understand the real causes of this problem, but basically it seems that I have the same problem explained here: https://bbs.archlinux.org/viewtopic.php?id=184340.
    The only difference is that there the OP says to have solved the problem with an upgrade to Linux 3.15.7, while it appeared to me with the upgrade to 3.18.3, and as I said it doesn't go away neither with a downgrade nor with another upgrade to version 3.18.4
