    Applied the ds locator policy to my computer did not help. As before, the domain name is pinged randomly to all domain controllers
    ipconfig /all

    ping my domain

    nslookup my domain

    Weights and priorities are set.
    Maybe somewhere else I need to configure?

    Hi,
    Let's make the questions more clearly.
    1, nslookup domainname will list all the DCs those have DNS records
    It is an expected behavior.
    When you run this command, the clients will query the DNS server it can contact to (in its local site).
    The DNS server have the records for all the DCs.
    The DNS server will response all the IP address it has to the clients no matter the clients can contact them or not.
    So, the result of the command: nslookup domainname doesn't mean the clients use all of them as DNS servers.

    It is suggested to capture the network package to find out which the DNS server was the client used.

    Feel free to let me know, if i misunderstand you.

    Best Regards,
