    Hi,

    We have 3 DC's running. All W2k3. All DC's have dns

    Our domain structure is a tree with 2 child domains:

    domain.xxx
    sub1.domain.xxx
    sub2.domain.xxx

    When i run dcdiag /test:dns on my dc it shows errors on all Root
    hints. I did search the internet on this problem but could not find a
    solution

    There dont seem to be a problem with any of the computers on our
    network with internet domain resolving but i worry because the DNS
    test fails on this.

    Please help me.
