  • Hello,

    please post an unedited ipconfig /all from all DCs.

    Do you have configured the Reverse lookup zone for your domain?

  • Hi,

    To allow nslooup for IP, you need a reverse lookup zone for your subnet.

  • Hello,

    on DC3 please remove the public DNS servers 8.8.8.8 and202.131.0.2, these ones shold be configured as FORWARDERS in the DNS server properties with the DNS management console.

    Also in the DNS management console you will see below the DNS server the Forward lookup zoneswhich should contain your _msdcs.xxxx.local and xxxx.local zones and below Reverselookup zonesyou should configure the used subnets in your network.

    Our other 3 DCs ipconfig is correct. I should add all DCs ip address in my network adapter?

    Thanks and regards

  • Hello,

    use at least 2 DNS servers on the NIC settings and as last one add always the loopback ip address 127.0.0.1
