    I am currently running 2003 Server to host a couple of web
    sites. I recently switched ISP and I have set up the DNS
    up but I still can't get my Websites to come up. I can
    broswe to them via IP address but I can't get the webnames
    to see it. I think it is on the ISP side of things. When I
    asked them they said I need to get a Third party DNS
    program to point my web server to them. I have never had
    any problem before switched. Any suggestions would be

    "Setup the DNS" is sort of vague -- are you having (mostly)
    a client problem resolving external names or are you having
    mostly a "server problem" where others cannot resolve your
    public DNS website and other names?

    If you have the latter and recently moved ISP and probably
    DNS servers, did you re-register/update this with the parent
    domain? (e.g., .com or through the registrar you use?)

    If the former (trouble resolving everything externally) are
    you running an internal DNS server (set) where you clients
    resolve? If so, you probably need it to FORWARD.

  3. 1) Figure out who your Registrar is.
    2) If not already, let your registrar host your DNS (*not your ISP.)
    Registrar dns hosting is mostly free (depending on registrar) for simple dns
    needs (i.e. couple A records, etc.) Get your ISP out of the picture in
    respect to DNS and even Web Hosting. Many public Web Hosters out there and
    don't need to rely on ISP as you may change ISP again and they tend to cost
    more then the big hosters. Check out for some good hosting
    3) Is Web servers at ISP or other Hoster, change NS delegation records at
    Registrar to the DNS servers of the Web Hoster (ISP) - they must supply this
    to you.

    They may be talking about a dynamic DNS utility, but it's hard to say
    from the description you give. Why don't you contact them and ask
    exactly what they need and then follow their advice?

    This may need to be clarified a little, so I am going to assume that the DNS
    for the websites you are hosting is not on site and is hosted elsewhere?
    You have a router or firewall with an NAT device, so that your server has a
    private IP address and you are using NAT to translate the public address(es)
    on your router to the private address on your server?

    Your ISP is correct, but you don't need a third party DNS unless you are
    also hosting the public DNS. Use DNS that is built into Win2k3 and set up
    forward lookup zones for the websites you are hosting. IF you are hosting
    only the websites and not any other services for the website you are
    hosting, you should name the zones for the FQDN of the site
    ( with a new host leaving the name field blank and give the
    host the private IP address of the webserver. This is so your DNS will pass
    on other queries in the domain ( to the proper Authoritative DNS
    server and return the proper IP.

    When you are behind NAT you cannot make an incoming connection to a public
    IP address on the public side of the NAT device. You have to make your
    connection directly to the private IP of the server.
