  • dns dynamic update dont work correct

    i have Domain controller and Dns and dhcp installed in windows server 2008


    but i have problem when i try to join clients in domain

    the cause

    dns don't have records (A record) for this clients in its databaes

    so dns can't register clients dynamic in its database

    but sometimes i find dynamic records for some clients

    while all settings is ok in dns and clients which cant register dynamic

    if i register clients static in dns it is working and can join domain

    the other thing :

    all clients use this dns server to go to internet by forward to router and then to internet

    so why clients don't register in dns server




    can any one can help me

    Hi,
    Are all three roles (DHCP, DNC, AD) hosted on the same server?

        You can do some test with domain member computers configured with fixed IP address. However I think the issue is DHCP running on DC.
        You should run DHCP service under a dedicated user account.
        Take a look into this KB.
