    Hello All,

    I posted a while back asking for help upgrading my single
    name domain to AD via Windows Server 2003. I am currently
    running NT 4.0 domain called MAIN. I am going to perform
    the actual upgrade in 1 week, but I ran into problems in
    the test lab. The install went ok, but I got confused at
    the AD install. Since I have a single name domain, and
    over 500 users, what option do I select for the domain. Do
    I set it for a new domain in an existing forest? Will I
    have to touch each workstation? I am currently using WINS
    and NO DNS!! All of my clients are static. Will I have to
    set DNS in each one?

    Backgroud: I have a single names domain. I am going to add
    an NT BDC to the domain, upgrade it to be the PDC, and
    then upgrade it to 2K3 with AD...

  2. Hi Bill,

    It's good you're doing an inplace upgrade on your Winnt 4.0 PDC, this
    process is pretty slick. When you get DNS sorted out and run through
    DCPROMO you will select (iirc)

    1 - Domain Controller for new domain (even though it is an upgrade, you will
    still have to setup a new AD domain with a FQDN city.main.local etc. and
    then the old sk00l netbios name -- which in your case will be MAIN)

    2 - Domain in a new forest (since you don't even have a forest yet, this is
    a good place to start)

    Also, read through:

    We added these keys on our NT4.0 pdc and bdc before we upgraded them to
    2003, all workstations just grinded along fine on Monday and the upgrade was
    (excluding some security permissions issues) fairly transparent to the

    You can keep running Wins if you want (and probably will have to for awhile
    yet), we run both at our shop though it's only for about 100 clients. Once
    DNS is setup, the only thing you'll have to do is make sure ALL the clients
    point to the internal DNS server (presumably your upgraded 2003 DC). If you
    want to keep your static IPs, you will likely get to (snicker) run around to
    the 500 machines and input the DNS IP address. Perhaps now would be a good
    time to do a switch over to DHCP so when things do change, you just have to
    update one machine and everything gets pushed out. Though, I don't get
    enough exercise anymore due to dhcp.

    Continue in your test lab, make sure AD is up and going and setup a few
    clients with static IPs to see how they actually integrate.

  3. Hi Bill,

    Thanks for your posting here.

    We need DNS service in Windows 2003 domain. When you upgrade NT PDC to
    Windows Server 2003, you can install DNS service on it and enable dynamic
    update in Windows Server 2003 DNS. It is recommend that you install another
    DNS server in your domain to ensure better performance.

    As for your clients, I would like to recommend that you use dynamic IP
    address, so you can assign the DNS and WINS to clients using DHCP.
