  • what will be preffered and Alternate DNS entries for PDC and BDC

    I have configured PDC and BDC in my domain.
    both are working fine.

    I have a doubt in DNS entries in both of PDC and BDC.
    Both PDC and BDC are also configured as DNS.
    I have configured IP address and DNS entries in both server as below-

    PDC IP address : 192.168.1.2/24
    GW : 192.168.1.254
    Preffered DNS : 192.168.1.2
    Alternate DNS : 192.168.1.3

    BDC IP address : 192.168.1.3/24
    GW : 192.168.1.254
    Preffered DNS : 192.168.1.2
    Alternate DNS : 192.168.1.3

    Can some body help me to confirm and clarify that these DNS entries are correct or not ?

    if you need some clarification pls revert..

    Thnx

    Personally, I would switch them so 1.2 has 1.3 as primary and itself as secondary. This enables each DC to register against the other when it boots up.

    You can use tools like dcdiag and netdiag to determine if things are looking healthy.

    Also note that there is no PDC/BDC as such anymore with 2000 and 2003 active directory.

      I would do it slightly different. I'd make DNS AD integrated and choose the relevant scope (All DNS servers on the domain For example). Ensure replication has occured.
      Then, I'd leave the first DC as it is and make the second one point at itself as primary. Nothing wrong with Andy's suggestion but I think this way DNS traffic will be minimised and AD replication will deal with both DNS servers zone consistency.
