DNS not hanlding recursive queries

    I have inherited a Windows 2003 SBS. The DNS is setup with forwarders and
    the server points to itself. However the server does not appear to resolve
    external addresses. On running the recursive external test on the monitoring
    tab I am getting failed error.

    Disable recursive is not checked on any place I can see.

    Not sure how to narrow this down.
    Thanks
    Chris

    Are root hints populated and resolved to IP addresses?

    Don't have access at the moment but there was a listing of root hints with
    IP addresses and I tested pinging the ip address which succeded as per MS
    troubleshooting

    Thanks

    Delete the "." zone if any.

    Set your forwarder to your ISP (or your
    caching only gateway/DMZ DNS server.)

    If that doesn't fix, work from the DNS server
    and run NSLookup against the ISP DNS to
    see if you can get through the firewalls with
    a request. (DNS server might be blocked.)

    I ran nslookup and IP Address of Forwarder
    the response was request timed out. Does this mean it is being blocked
    Thanks

  6. How did you run nslookup? Can we see the output?

    What Herb is saying is to run nslookup like this:

    C:\>nslookup
    Default Server: london.nwtraders.msft
    Address: 192.168.5.200
    Then it will use that server.
    Then type in something like:

    www.microsoft.com

    And see what the output gives you.

    "Ace Fekay [MVP]"
    Actually what I was saying is run it like this:

    nslookup -time=10 TARGET dnsServerIP

    Time can be left out if you have no trouble.
    dnsServerIP is usually an IP address for the
    particulary server you wish to try.

    I seldom (purposely) run the NSLookup shell.

    No, but it means your internal server is not likely
    the source of the problem.

    Forwarder might not BE a DNS server, forwarder
    might not be able to reach the internet or indeed it
    might be because the request is blocked.

    But if a regularly client cannot ask the forwarder
    a question the problem doesn't lie directly in the
    (internal) DNS server software.

    Agreed, but I had told him earlier to run this FROM
    the command line of the DNS server to determine
    if THIS (same) machine could make a DNS request,
    while getting the DNS server out of the sequence.

    Of course, another easy way!

    Hope all is well Obi. Haven't seen you out here lately, but I haven't been
    out here too much lately. Alot on my plate lately as I'm still teaching, now
    just took over as an IT Director for a firm in Philly, and taking online
    classes. Oh boy!...

    :)

    Ace, I get a kick out of the times when I do see you here two or three times
    per week you'll start firing off responses to all the unanswered threads at
    once. Sometimes when I see your name behind just a single one, I'm
    thinking, "Here's Ace, there'll be a comment to all the open/unresolved
    posts here shortly"... <g>

    LOL

    I've been pretty busy lately, and try to answer posts in a more consistent
    fashion, as I used to. My schedule is so hectic, between teaching, sometimes
    doing doubles (day/eve), IT Director (part time) for an advertising agency
    in Philly, and taking online classes, I don't know where I can find time
    anymore.

    But I still try to help out, as you'e seen, one way or another. I'm glad
    someone noticed! LOL

  14. In Todd J Heron <> made a post then I commented
    below


    Man, I am so out of it, that I noticed I am being repetitive! I posted the
    same thing in the other post that I replied to you about my plate full of
    stuff to do. I need some sleep. Gots to lay off the caffeine!

    Ok, no coffee. But this shot of Crown Royal and cold Coors Lite tastes
    great!
