W2k3 will not tranfer or reload zone from master

    I am attempting to use w2k3 enterprise to provide secondary (slave) DNS
    service for a couple of zones hosted from a Linux server running BIND. I am
    not experiencing the documented incremental XFER issue that MS has a KB on.

    My issue is that (both of) my AD servers will not even attempt to reload or
    transfer the zones from the master (BIND) server. I've triple checked all the
    settings on both sides and do not see any issues with the configuration. I've
    also checked for connectivity between the two servers. I've even deleted the
    zones on the Windows servers and recreated them. One of the zones I'm trying
    to add is brand new and the other is an old one that I'm trying to update the
    zone on (it's about a year behind on the serial # it has vs. the new one).
    When I right click either zone and select reload from master or transfer from
    master it instantly fails without any explanation in the event logs. Also I
    never see any attempt to transfer according to my Linux server logs.

    Can anyone help? This is extremely frustrating and I need to get DNS service
    up for these zones ASAP on my AD side of my network.

    Thanks!

  2. Do you have a firewall blocking traffic. Maybe the network folks put up a
    firewall you are unaware of.

    Have you enabled dns debugging?

    Have you attempted to run Wireshark to see if you see any traffic on the
    wire?

    Have you run any diagnostics at all such as dnscmd?
    dnscmd /zoneinfo zone_name_failing

    Silly question: Can either AD server query the master server via
    nslookup or use it as their DNS server?

  4. As Paul mentioned, I would suggest to use Wireshark to determine if the
    transfer request is actually reaching the master. Keep in mind, TCP & UDP 53
    both need to be opened to make this work.

    Hello Paul,

    No firewall blocking traffic. I can telnet to port 53 both from the Windows
    server to the Linux server and vise versa.

    I do not see any attempts in the BIND logs on the Linux server where the
    Windows server even tries to contact it when I force reload and transfers
    from the Windows slaves.

    I enabled debugging, restarted the DNS server and attempted to transfer and
    reload the zone again from the master and I get nothing relating to transfers
    in the debug file. The only thing I have in there is normal activity.

    Wireshark traces show SOA queries to the Linux server upon manually doing
    "transfer from master". When the Windows server does the standard query SOA,
    the Linux server returns the standard query response with the domain name,
    type SOA and then a list of root servers.

    Shouldn't the Windows server request a zone transfer rather than a SOA query
    if it wants to receive a copy of the zone?

  6. That's unusual. Telnet uses TCP, so that's not the best thing to test it
    with. Transfers use UDP. Is anything blocking UDP, such as on the server
    itself (a security app?) or in the firewall? If you delete the secondary,
    and recreate it, does it work?
