  • Odd DNS issue..

    Hey everyone,

    Hope all is well-


    so I'm trying to transition from the land of sbs to a bigger scale of servers (ie more than one lol)


    I set up DHCP on my server 2008 r2, set up reservations.

    The problem is with DNS.. I have tried to follow maybe 5 or 6 tutorials from youtube, microsoft, and google, but nothing is working.

    The two clients I have are set to static ip's with the reservations I set up.

    ..when client1 tries to ping the dns server, it goes:

    pinging DNSserver [IPv6 address]
    Requested timed out x4


    I certainly didn't set up IPv6 lol

    Any ideas, or can you point me to a GOOD tutorial?

    Thanks in advance..

    Well....
    A) What happens if you ping the server by IPV4 address? i.e. 10.1.1.1
    B) That looks like it could be a problem with DHCP.
    Two things:
    1) If I wrote something wrong please please please let me know. I want to know ESPECIALLY if I am wrong.
    2) I have a tendency to write things that are misconstrued as being agressive or not so pleasant. That is not my intent.

      Use the following command to ping the IPv4 address:
      Code:
      ping DNSserver -4
      But this is not a DNS issue, this is a ping communication issue. If the firewall on the server isn't allowing ICMP traffic then you won't get a response from the DNS server.

      Are you sure the DNS service isn't working? You can test with nslookup:
      Code:
      nslookup
      server <ip address of DNS server>
      <FQDN of local server>
      Could you also explain your environment and what you expect to be happening? Without more details it will be pretty hard to help.

        Environment / background:

        I want to transition out of the Land of SBS and move onto bigger scales.. so what I'd like to do is:

        s2k8 r2: dns, dhcp, microsoft tmg
        s2k8 r2: data server
        s2k8 r2: exchange, etc

        I "configured" dns and dhcp on the first server, one nic card set to a static, followed some tutorial I found, and set reservations for the mac address of the other two servers; just trying to get connectivity.

        set the nic's to static regarding the same ip info as the reservations.
        I usually have a LAN router, first time I'm trying to use a server for it.
        The public nic can connect just fine on the first server

          OK, that's a little bit more info but it still doesn't explain what problem you're having and what your expected results are.

          Have you already installed TMG on the server?
          Where is AD installed?
