I can'f Force DNS Replication RRS feed

  • Question

  • I have an environment whereby internal domain name is the same as external domain name (website).

    In order to access the website internally, I had to create an A record that points to external webserver. Unfortunately the changes are not reflected on clients machines. But I can access the website from the server.

    When I ping the website address via dns server, it picks up external webserver ip. When I ping via client machines, it returns internal dns Ip

    My environment (Win Server 2012  STD)

    cls

    When I tried to force replication, I get this error:

    C:\Users\Administrator>repadmin /syncall /aped
    CALLBACK MESSAGE: Error contacting server CN=NTDS Settings,CN=HYPERV01,CN=Server
