Thread: DNS issue

  1. DNS issue

    We have an issue with our inhouse DNS. We have one server that is not a DC,
    it is a domain member however. We have clients that will have no issue
    connecting to this server and then all of sudden they can not connect.
    Instead the client will be redirected to our main DC that host the GC. If
    we flush DNS on the client or restart the client it will connect again fine.
    It is very sporadic, and will happen on one machine one day and a different
    machine another day. I checked all DNS settings on our server and they
    look correct. I even took them out and put them in Manually once, another
    time I deleted them and ran ipconfig /registerdns on the server that we can
    not connect to and it seemed to register correctly. Can anyone shead some
    light on what the heck this may be?

    This is not really a group policy issue - meaning you could have been
    more judicious in your choice of cross-posted newsgroups.
    Perhaps a post only to microsoft.public.windows.server.dns ???

    Anyway, when you said

    indicates that the client has been given an invalid IP since flushing the
    client will not change its current in-use DNS server (for that use
    net stop dnscache / net start dnscache). Hence, your question is how
    did the client cache get poisoned?
