Dns Problem RRS feed

  • Question

  • Hi Everyone

    This time i have issue with my DNS. So Please  guide me.

    I am using Active directory  integrated dns and using forwarding.

    My Ad Integrated Dns is A.in and its Ip Is 192.168.10.42

    and forwarded Dns is same A.in its Ip Is public Ip

    due to this reason when i open website WWW. X.A.in it will Not open.

    When I open other website it will be open

    Any solution Please guide me.

    previous user mail ID user@A.IN  After Exchange Setup they Want same mail ID With Exchange. Due to this reason we are using A.IN Dns and forwarding this with A.IN.

    This is basic requirement of businesses,

  • HI Muzaffar,

    IS it happining to all the users of only for single PC. YOu can try belwo

    Assign a Manual DNS on Effected pc as 4.2.2.2 and test the connection, if everything is fine then try removing 4.2.2.2 and add the DNS forward IP as client DNS directly,

    We will come to know whether the issue is with Public DNS or AD

    If Issues with Foward DNS : Change the IP address to Different DNS server

    IF AD DNS is not responding, restart the services and see if you have any error on Event

  • This Is happining to all users and all Pc. I have already assigned 4.2.2.2 and test but still facing same problem.

    This is only Warning in Dns event

    The DNS server is waiting for Active Directory Domain Services (AD DS) to signal that the initial synchronization of the directory has been completed. The DNS server service cannot start until the initial synchronization is complete because critical DNS data might not yet be replicated onto this domain controller. If events in the AD DS event log indicate that there is a problem with DNS name resolution, consider adding the IP address of another DNS server for this domain to the DNS server list in the Internet Protocol properties of this computer. This event will be logged every two minutes until AD DS has signaled that the initial synchronization has successfully completed.

    I Think i will explain my problem Clearly

    My AD Dns Is Nic.in

    And It is forward on main Nic Dns ( Nic.in)

    All website will be open Except those nic Site is not open

    When i open X.nic.in not open, B.nic.in, C.nic.in and all other site will open

    Like gmail.com, google.com, gov.in,

  • HI Muzaffer,

    Just to summarize ,

    You have an AD integrated DNS server with Domain Name as NIC.IN

    All Client are Joined to the Domain NIC.IN

    You are forwarding the DNS to another DNS server NIC.IN so both DNS servers are having Same name ?

    When a user access any site from internal DNS server example , Xyz.nic.in , bby.nic.in, the users are not getting the Webpage.

    If I understand correctly, Please try the below

    • On the forward Lookup Zone of  NIC.in on your AD DNS
    • Create a Host record ( Example If your Site is XYZ.nic.in, then create a Host record as XYZ and Point to the IP address of the website )
    • Nslookup the Website, now you will be able to resolve the IP address
    • Now IE will route the traffic to the required IP address
    • If your site is hosted internally / then Add the Internal IP address

    Let us know the result

  • Hi Guna

    Thanks for quick responce

    But problem is still same because xyz is not internal Site. All mention above site is hosted to EXTERNAL. I have done this things last night.

    Can we local dns forward to same name of external dns?

    Because all site will open only nic.in site is not open.

  • Hi Muzaffar,

    Can you add a Host record on your internal DNS of the Webste and point the IP address as External.

    All we need is DNS to resolve.

    If XYZ.NIC.in is the site

    and Public IP is : 195.2.x.x

    The Create a Host Record on your internal DNs and point to Public IP

    ----

    Do a NSlookup on the client and see if you are able to get the correct IP address.

  • Dear Guna

    This is very tuff task because a lots of nic website and user can access any site any time . Any other solution.

  • HI

    HI Muzaffar

    Not tuff,this is the best way to do ..

    Since you have both DNS on the same name, You need to create a record on you internal DNS server for the site to work.

    Example :

    Internal  DNS NIC.in is 10.10.10.1

    External DNS NIC.in is 195.x.x.x

    You are forwarding DNS from 10.10.10.1 to 195.x.x.x

    When you browse a site called X.nic.in it will look on 10.10.10.1 and if no record is found then it will not forward the request to 195.x.x.x as for the client 10.10.10.1 is what holding the full DNS of the domain.

    Your need to have all record on internal DNS, Its Split DNS
