DNS Server not resolving properly.

Posted on 2006-04-24
Last Modified: 2010-03-18
I currently have 3 network cards in my DNS server.  2 network cards are Natted to have an extra gateway in my network.  The 3rd Network card is my DNS server IP address.  When I ping my DNS server, I get one of the Natted Ip's returned.  I need to be able to ping my DNS server and get the correct IP returned.  I have a back up DNS server with the same exact Network settup to have an extra gateway.  But that IP returns just fine.  Please help me out.  By the way, is anyone familiar with a program called SIMPLE DNS.  If so, I have other questions about this software.  Thank you.

    I am not familiar with SIMPLE DNS, but I'm not sure what you mean when you say an IP is returned with a ping.  If you mean that the name is resolving to the wrong IP when you ping by name, then you will have to turn off the automatic DNS registration on those NICs.  Go to the network properties for those NICs and then to the TCP/IP properties.  Click the advanced button and goto the DNS tab.  You should be able to turn off the automatic registration here.  You'll probably also have to delete the records from your DNS server, or they will stay there until scavenged.  Also make that NetBIOS

    When you say that you need a second gateway, you don't mean that your have 2 network cards in the same computer configured with 2 different default gateways, do you?

    Also, see if NetBIOS over TCP/IP is running.  It probably shouldn't be on any of the NICs.  Otherwise, there is the possability of broadcast resolution which you don't want.

    Ok, adamdrayer...

    Looks like that worked.  So I pose the question to everyone once again about SIMPLE DNS.  does anyone have any clue about this application.
