Setting up Your Internet Address; managing your domain yourself

Discussion in 'Windows Small Business Server' started by Allistair Lomax, Oct 12, 2008.

  1. I'm just preparing to upgrade to SBS 2008, and I'm just carefully reading
    the documentation. (Wow! This has to be first, I normally just bung the
    discs in, mess up, then turn to the documentation).

    I was just reading the section on setting up your external domain name, and
    I have a number of questions.

    The following pertains to me;

    1. I have an existing domain
    2. The SBS 2008 will not be able to manage the domain name and settings for
    3. My ISP provides a seperate web-based management interface, that sets the
    DNS records for my Domain

    I'm guessing I'll have to manage the domain myself and set up the DNS
    records as directed in the documentation.

    First question, anyone else out there gone down this route and have some
    practical suggestions, gotchas, screen-hots etc?

    Second question, I have another domain that I use for email only. My current
    Exchange Server is configure to forward addresses on this other domain, on
    to my primary domain. Is this possible under SBS 2008? Is so, how this pan
    out, configuration-wise?

    Many thanks,

    With SBS 2008 .local is assumed for the tld unless you use an answer file
    during the install. If you're migrating as Allistair is then it will use the
    existing domain name. If not migrating and you don't want .local you must
    figure this out before starting the install.

    By upgrade I'm assuming you mean upgrading from SBS 2003 to SBS 2008.

    For the first question your guess is correct. If you use a registrar that is
    not supported by the wizard then you manage the external DNS yourself, just
    as in SBS 2003.

    For the second question I'm with Cliff. I don't really understand the
    question. Maybe you can rephrase it. I think you mean your SBS server is
    receiving email for two domains and the mail from both domains is delivered
    to the mailboxes from one domain. Yes, you can do this in Exchange 2007 as
    well. I don't think the migration documents cover how to migrate this.
    You'll probably have to set it up manually but I could be wrong. I've only
    done a couple of migrations and never one with that scenario.

    As for gotchas there is one big one. There are no in place upgrades, only a
    migration scenario. This means you need two boxes, although they don't need
    to be physical. It is imperative that you have a verified backup and know
    how to restore it. There is no roll back to the old server. The old server
    is toast after the migration. You can format it and install a different OS
    but there is no way to go back to SBS 2003 without restoring from a backup.
    Because of this I'd recommend you do the migration as quickly as possible.
    You can stretch it out over a month according to the documentation but if
    something goes wrong at day twenty you will be restoring back to before you
    started then trying to move the data from day one to day twenty off of the
    aborted 2008 server.

    It is very important to read the documentation very carefully and make sure
    you have permissions set as specified and you are logged in as the specified
    account when doing the various operations. Double check before each step. If
    you make a mistake you will probably have to start the whole migration

    Be very careful with time, dates, and time zones. When SBS 2008 is installed
    the time zone may be set differently from the SBS 2003 server. This may
    cause some problems during the migration, particularly if you are using
    virtual machines anywhere in the process. Make sure all of the machines
    including the hosts are set for the same time and time zone.

    Take a look at If it's not already available they will
    shortly have a much cleaner migration scenario.

    Thanks, Kerry,
    Actually, this is, (was, I did the install, yesterday), a clean install on a

    In regards to managing your domain, am I correct in assuming that the four
    DNS records outlined in the table on the page entitled "Setting Up your
    Internet Address", need to set up at ISP's domains and NOT on the SBS box?
    You are correct. How is this done in Exchange 2007?

    What document are you referring to?
    I've never set this up with Exchange 2007. The first two links here look

    Thanks Kerry,

    Could you give an example of the second MX record should look like?

    The documentation describes it as "MX Alias (CNAME)
    Provides e-mail message routing for to arrive at your
    Windows SBS 2008 mailboxes.

    I always thought an MX record was not the same as a CNAME record.

    Thanks in advance,

    I prefer to create an A record for then point the MX
    record to the A record. I don't know why they want to use a CNAME record
    instead of an A record. Maybe someone else knows the technical details.
    Personally I thought CNAMEs weren't supposed to be used in MX records but
    I'm certainly not a DNS expert.

    Thanks for your help, Kerry, much appreciated.

    I submitted a comment to MS about that part of the documentation. I
    certainly think it needs clarification
