    Just need some guidance on best practices for setting up dns on sbs2003.

    I've got a basic default setup and everything seems to be ok.

    Does anyone know any good sites that will guide me through all the tweaks
    and making it more robust

  2. Hi Peter -

    DNS on an SBS lan is usually pretty straight forward. All of your
    workstations should be pointing to your SBS (and *only* your SBS) for DNS.
    Your SBS should have your ISP's DNS servers listed as forwarders. DNS
    should only be listening on the LAN nic.

    You aren't trying to host public DNS for your domain, are you?

    I also like to use two different ISP's DNS servers as forwarders for
    kinda redundency

  4. Hi Kenji!

    Generally, hosting public DNS on an SBS is advised against for several
    reasons. One, the typical SBS has enough to do without handling public DNS
    requests. Two, Windows doesn't handle split DNS very well, so it's very
    difficult to keep your internal DNS namespace separate from your public DNS
    namespace. Three, you should really have a minimum of two servers providing
    public DNS services, and you would ideally want them not only on different
    internet connections, but at different physical locations, so that if your
    internet access fails or you have a power outage, etc., you still have a
    publicly accessible DNS server. Finally, it's currently just too easy to
    control your public DNS records with most of the hosts out there - you
    actually control the records, but the external host maintains the servers &
    the redundancy . . .

    And don't mention the KB - no problem :^)

    You might suggest to the Japanese user that he get his ISP to host the DNS
    for him. Alternatively there are free DNS hosting providers like

    Once you remove cost there is absolutely no benefit to have your own Public
    DNS servers unless you are running a web farm. (If that were the case, two
    Standard Servers would be better but your could also use an appliance...
    whole otheer topics though)
