  • Huge DNS trouble

    Hi guys

    I really don't know were to start. But I have big trouble with our internal DNS. Sometimes, not all the time, when I try to ping a computer it responds with our old external IP address (we have moved to a new office a few moths ago). If I make a tracert the first response I get is our Gateway, why?

    i.e.

    ping testserver
    The respond is: pinging testserver.domain.com [old external IP]

    If I use nslookup and set our DC as server I always get the right answers.

    Our environment is two DC (windows server 2003 32-bit) and a bunch of Vista 64-bits clients and a few 32-bits clients (including server2003, xp).

    Please, any suggestions?

    Homer,

    ping testserver
    The respond is: pinging testserver.domain.com [old external IP]

    Is this happening from all the PCs in your network, if not then could be a entry in host file.

    Also add a static entry for this server in DNS

    If you are using DHCP then make sure that users are getting correct DNS servers.

    Also under DHCP properties>DNS tab make sure following buttons are selected.

    1. Enable DNS dynamic updates according to the settings below
    A. Always dynamically update DNS A and PTR records

    2. Discard A and PTR records when lease is deleted

      Don't no if all have the same problem, but some have noticed the problem.

      Done! Thanks!

      I'll get back if the problem persists.

        Okay, this sucks. I still have some problems with my DNS. But I don't think it is the DHCP nor the DNS server that is the problem. It might be Vista that causes the trouble.

        If I make a restart of my computer and then try to ping any computer in my organisation it gives me the old external ip. When I make a "ipconfig /flushdns" and then pinging any computer it shows me the right ip.

        Something crappy is stored somewhere, but I don't know where.

        help please.
