ISPs DNS Server changing

Posted on 2011-05-05

I received a notice from our ISP that they are retiring their legacy DNS servers.  Is all I need to change is my DNS servers in DHCP on my 2003 Small Business Server?  My router/firewalls shouldn’t need re-configured, correct?

    Not in DHCP. DHCP should be configured to *only* list your SBS as a DNS server.

    You'll make the change to the DNS forwarders on the DNS Server snap-in on the server. That is how SBS handles DNS queries it receives from clients that it doesn't have cached and can't answer. It recursively queries the forwarders.

    Is that is the same with server 2003 standard?

    1.Open the DNS snap-in on the DNS server (go to Start | Administrative Tools | DNS).
    2.In the console tree pane, open the Properties sheet for the DNS server you want to configure by right-clicking the server name and selecting Properties.
    3.Click the Forwarders tab.
    4.Enter the IP address(es) of the DNS server(s) you wish to forward requests to.
    5.Click Add.
    6.Click OK to close the Forwarders tab.

    If you are using a DNS server role on 2003 standard and it resolves both internal AD and external resources, yes, the advice applies to non-SBS installs as well.
