    I am attempting to upgrade our systems to Win 2k from NT 4.

    I have created a new DC in NT 4 and promoted it to a PDC. Then I upgraded
    the new PDC to Win 2k.

    When I installed Active Directory, the DNS portion of the wizard confused me.
    Our original PDC was also the DNS server, and contained zones for resolution
    of our corporate web sites, duplicatiing entries at the ISP. This doesn't
    sound right, but the DNS forwarding didn't work in NT, so we made entries so
    that users and servers would be able to access the corporate web site.

    Anyway, the DNS server has a zone for "ourcompany.com", with two subdomains
    for branch offices.
    Confusion point number 1: Should the domain be named "ourcompany.com", or
    something like "hq.ourcompany.com"? The wizards were not clear on these
    points.

    When the wizard installed DNS, the test came back that the original DNS
    server could not support dynamic DNS. I created a new zone for
    "hq.ourcompany.com", and then created a secondary zone for "ourcompany.com",
    pointing to the original DNS server.
    Confusion point number 2: It wouldn't let me do a transfer using the right
    click menu. Do I need to make the NT DNS secondary, and then make the 2k3
    primary?

    Eventually, I will decommission the 2k3 server, once I have migrated the
    other DC's. What steps do I need to take to move it to the original PDC? Just
    do a transfer?

    Thanks for the help in advance!

    Hi,

    Thank you for posting!

    I wondering how much domains in your network. I can see there are three
    domains in DNS configuration. ourcompany.com and its subdomains like
    hq.ourcompany.com. However, how about the Active Directory domains in the
    network? As you have upgrade the NT PDC to Win2K. I suppose that the FQDN
    of this domain is ourcompany.com. So for your first confusion point. The
    domain name should be the same as the domain which has the DNS server, for
    example, ourcompany.com. I wonder if you plan to create another two domains
    and make them as the subdomains of the current one.

    Please understand that there are lots of different between Windows NT
    domain and Windows 2000 domain.

    Here are some step-by-step guides for Windows 2000,

    If I am off the base or there is any misunderstanding, please feel free to
    let me know.

    Have a nice day!
