Setting 127.0.0.1 as Preferred DNS on a Domain Controller

    Hello,
    I would like to check whether setting 127.0.0.1 as Preferred DNS on a Domain
    Controller is a best practice? The server is built as a Domain Controller and
    DNS server. By default, once dcpromo has been completed with auto configure
    DNS function, the default Preferred DNS is set to 127.0.0.1

    So i would assume this is a best practice from Microsoft or it's best to
    configure the real IP of the DC as preferred DNS?

    TQ

  2. both will target the local server. the 127.0.0.1 config will for example not
    be impacted by IP changes

    jorge, thanks for your response. you're very helpful in this forum,
    especially on my previous question regarding AD Site Link.

    so, if i get you correctly there is no wrong or right answer to whether
    assigning the physical IP or 127.0.0.1 to the domain controller right? my
    concern is whether using 127.0.0.1 will create any replication issue among
    the DC as this was raise up by some of the seniors in the company...

    thanks

    The DNS server should be set to the IP address of the DC. The alternate
    should be set to one of any other DCs in the domain.

    Some recommend the opposite.

  5. Officially it is not the best practice.

    Unofficially it works just fine everytime I have tried it.

    Someone commented that it would be immune to some degree to IP related
    problems because 127.0.0.1 would always point to itself no matter
    what,...and I agree with that.

    But "officially" it is not considered best practice,...but I don't know why.

    thanks guys for all the feedback.
    i think i'll just use back IP address of the server instead of 127.xxx
    :)
