Slow Connection of Process History View

Dear All Fellow Community,

I have question regarding the subject. I've already follow the KBA from Emerson but still have trouble with it.

The problem is I cannot delete the zone that I don't want to use on Reverse Lookup Zone. Only for the 8.10.in-addr.arpa that I can delete. Are there any other way to delete it? dnscmd tried but not recognized. Please help me on this matter Thanks.

    Hi,
    I'm not sure because if we follow the KBA suppose 8.10.xxx is the one zone there am I right? For the 8.10.xxx I surely can delete but for other I can't delete it. Need help on this

    Hi,

    What KBA are you refering to? What DV /win version are you using?

    you can start by reading eg. this https://social.technet.microsoft.com/Forums/windowsserver/en-US/70438c0b-7ae1-44ee-940a-6f6f35fc6947/can-i-safely-delete-and-recreate-reverse-lookup-zone-in-ad?forum=winserverDS

    You could aslo try scavening the records to clean them...

    Nobody can change the resolution since they all are in DeltaV Desktop mode, how did it start I also didn't have any idea.

    I've already check network diagnostics and all of them are working fine.

    Last time one of the guys from emerson already come and only delete and create new Reverse Lookup Zone, I don't know how to delete other than 8.10.xxx.

    For 8.10.xxx it will show Delete option.

    For other 3 no option for delete, that is the problem I'm facing right now

    Where's your DeltaV Primary network reverse lookup, you don't seem to have 10.4.x.x configured?

    Have a look at the interfaces tab for the DNS server and make sure you are only servicing DNS on 10.4.x.x & 10.8.x.x subnets, 127.x.x.x and any other IP's are de-selected from the bindings.

    Hi Adrian,

    Can I know how can I de-selected or delete the unused configuration?

    Hi,

    here is some info from the MS sites (https://technet.microsoft.com/en-us/library/cc940772.aspx)

    DisableAutoReverseZones

    This topic has not yet been rated - Rate this topic

    HKLM\SYSTEM\CurrentControlSet\Services\DNS\Parameters

    Data type

    Range

    Default value

    REG_DWORD

    0 | 1

    0

    Description

    Enables and disables automatic reverse zones, an optimizing feature of the Domain Name System (DNS). When this feature is enabled, DNS automatically creates three reverse lookup zones.

    Reverse lookup zones enable the DNS server to be authoritative, that is, to know the answer in advance and to respond immediately to the most common name queries, eliminating unnecessary recursive queries. In accordance with pertinent Requests for Comments (RFCs), by default, the DNS server is authoritative for three reverse lookup zones:

    • 0.in-addr.arpa (0.0.0.0)
    • 127.in-addr.arpa (127.0.0.1 - loopback)
    • 255.in-addr.arpa (255. 255. 255. 255 - broadcast)

     

    Value

    Meaning

    0

    The automatic reverse zones feature is enabled. The DNS server automatically creates three reverse lookup zones.

    1

    The automatic reverse zones feature is disabled. The DNS server does not automatically create reverse lookup zones.

    Change method

    If Microsoft Product Support Services instructs you to change the value of this entry, use Dnscmd.exe, a tool included in the Windows 2000 Support Tools, and then restart the DNS server.

    Activation method

    Because the DNS server creates zones only when it starts, you must restart the DNS server to make changes to this entry effective, even if you use Dnscmd to make the change.

    Note

    DNS does not add this entry to the registry. You can add it by editing the registry or by using a program that edits the registry, such as Dnscmd.exe.

    Caution

    Do not change the value of this entry unless instructed to by Microsoft Product Support Services. Using automatic reverse zones improves the performance of the DNS server. The default value is optimal for almost all DNS server configurations.

     And they also say like this :

    As Meinolf has pointed out, there is no reason for concern. As per http://support.microsoft.com/kb/198410

    "clients sometimes query for standard IP addresses such as 0.0.0.0, 127.0.0.1 (loopback), and 255.255.255.255 (broadcast).

    By being authoritative for the zones corresponding to these queries, the DNS server avoids unnecessary recursions to the root servers on these queries."

     

    Hope this helps..

    Hi Niklas,

    Do I need to disable it or? And I found something else at Forward Lookup Zones since I saw yours only have one, I must kept one or just left it 2?

    Thanks for your support.
  • In reply to Raimi:

    Hi Raimi,
    the picture is just some fast setup on my virtual server machine just to show you were the interfaces tabs are.
    Did it say in the KBA that you should delete all of the records in the Reverse Lookup Zone ?
    you can easily delete the DV server that you have and add Both DV server ip adresses or/and if you have secondary DNS server?
    Do you have the KBA number?

    Hi Niklas,

  • In reply to Raimi:

    Hi Raimi,
    read the KBA...
    If you delete the 8.10-xxx lookup zone then you have the instructions in the KBA how to add the zone back..

    If you are unsure, please contact your local Emerson office for additional support...
