  • DNS Probs

    Hi all
    Just found this forum so 1st things 1st Hi to you all.

    Im new in the world of IT and im having some trubble with are 2003 R2 server,
    The main problem is with the DNS as it kinda gone nuts on me.

    Not letting me add new clients to are domain and messing with are domain polices/will not let me edit them. unknow user.

    Have been looking into this for a bit and have found what im 99% shore it the route of my DNS trubbles.

    Some how at some point are server name have got mest up,its gone from.

    NEWTON to NEWTON.192.168.1.2 so now are FQDN would be,
    NEWTON.192.168.1.2.MYWORK.LOCAL.

    It should be NEWTON.MYWORK>LOCAL.


    From reading whats on the site its looks like im shawed

    As i cant rename it if im right?

    Dose this main im looking at a full fresh install/setting up all accounts/ and so on.

    If its a must and the only way to sort this i will just have to take the hit and plan for time to do it just having to copy every users files and so on from there old accounts on there pc to the new 1s will be a big pain.

    Well hope thats all clear so if its not.

    Any help would be appreciated.

    Re: DNS Probs

    So has your domain name changed then???

    Can you post an IPCONFIG /ALL from your DC??

    Check all your DNS suffixes and make sure they are mywork.local

      Thx for the reply wullieb1

      I have hand a look at the primary dns suffix and its 192.168.1.2 lol i take it im right in saying this should be mywork.local ?

      AD still shows the domain as mywork.local so thats looks ok.

      Whats the best way to correct the primary dns suffix so it reads mywork.local ?

      Thats if it can be or even if its safe to do so.

          Depends on where it is set.

          Usually there are 2 places that it can be set and one is generally set when you join the domain and shouldn't be changed.

          Check the DNS Suffix on your network card settings and change that to be mywork.local if its not.

            Thx wullieb1

            The dns suffix has never been done via the network card at any time but will see if adding it there will fix the problem and thats as soon as i can fit it in as its are main DC and cant have it falling on its ass .

            Will post back on how i get on.

                  Re: DNS Probs

                  Thats where your problem lies.

                  Go into the Network Card properties and then TCP/IP properties then click on the Advanced Button.

                  In there you will see a DNS tab. Click on this to see the Advanced DNS settingsd for that network card.

                  I would reckon you have entreis in the Append these DNS suffixes so delete them.

                  Also change the DNS Suffix for this connection if it is used.

                  You can also check the other DNS suffix setting by right clicking My Computer and selecting properties. Click on the Computer Name tab then click on the change button then click on the advanced button and change any DNS suffix in there to youor domain name.

                    Re: DNS Probs

                    Ok have looked at the DNS settings on my network cards and none have had any added DNS entry put in.

                    I cant change or look at DNS in My Computer tap as the change button is grayed out.

                    With Note:The identification of the computer cannot be changed because The Certification Authority Service is installed on this computer.

                    So take it the only way is to add mywork.local to the DNS suffix of this connection box in the DNS tab of the network card in use.

                      Re: DNS Probs

                      Nope it looks to me like your Primary DNS suffix is causing you all the problems.

                      When you joined that machine to the AD Domain how did you do it???

                      As said before the AD name is generally the Primary DNS suffix.

                      Worst case scenario you will either need to move or remove the Certificate Authority from that server then remove and readd to the domain.

                      As a thought what is the computer name as shown on the My Computer, Computer Name tab???

                          Re: DNS Probs

                          Computer name is coming up as NEWTON.192.168.1.2.

                          Take it will be fine to just do a backup of the Certifivation Authority and uninstall it and then change the DNS suffix using the change name tab,
                          and when thats done and looking fine reinstall the Certifivation Authority and restore the backup.?

                          Or dose it need to be moved to a Temp server ?
