  • Please Help - Proper DNS/DC Nic properties

    I have searched up and down across the net for the right answer.

    I have 2 win 2003 dc's with dns and wins on them.
    Running on separate vlan's across a router.

    All dns works fine but I get intermittent event id's and just today dcdiag failed and then rebooted all worked fine.

    Should dc 1 point to itself first or to dc2 and itself 2nd?

    Then for dc2, itself first and dc1 2nd

    does dc1 point to dc2 first, etc.

    THANKS in advance.

    In Windows 2000 (pre SP3 I think) you could create a 'DNS island' by pointing a DNS server to first ask it self.
    In Windows 2000 SP 3 and later (including Windows Server 2003) this is supposed to be fixed.
    If I recall right I think that in Windows Server 2003 DNS it is 'best practise' to point your DNS to itself.

    Are your zone AD integrated?
    What exactly are the events you receive?

      It might not be dns or anything at all but I do get the same errors whenever I Reboot my dc's.

      I get
      2510 source server -The server service was unable to map error code 998.

      I can't find anything on this anywhere?
