Single VPN, multi site, multi DC, resolves multiple IP for domain RRS feed

  • Question

  • Hi all

    Not sure this is possible, but here goes.

    I have a multiple site domain

    Remote users create a VPN into thier most local site

    VPN client uses most local AD DNS server

    When connecting to resorces via \\domain.name I see massive delays, and am assuming this is because the DNS server is throwing back IP addresses of all DCs accross all sites, and the VPN connection only allows remote PC to access most local subnet.

    Is there a way to have DNS respond with only the most local addresses, or am I trying to invent something that should be achieved with a better VPN connection?

    Cheers

  • Hi,

     

    Thanks for posting here.

     

    In regard to your issue of making DNS server respond the most closest local IP address of dc, the method I can find so far is to delete unwanted A RR( same as parent folder) in your DNS server. I have test it in my environment, it worked successfully.

    Then you can use ‘nslookup domain name’ to check the reply, which will only contain the IP address of DNS server you wanted.

     

    But delecting these record may cause some unexpected problem during AD domain service( so far I haven’t experience these problems in my environment) . So it’s not suggested that you take this action if not strongly needed.

     

    Test result:

    Hope my answer will help you. Thanks!
